Groups

The socion (32 types) can be cut into small groups in many ways. This page lists every group that appears in the header "Groups" menu, organized by how each is formed, how Kasiukov's group theory classifies it, and which trait axes it shares, which classical relation structure it has, and which relations Model K contains, and links to each detail page.

What Is a Group ── One Person Belongs to Multiple Groups

The Seeker (ILE-Q) belongs to the α quadra, belongs to the Research club, falls in the Frozen group on stress resistance, and is a member of the Heritage Ring (α→−δ→γ→−β) within the Succession Ring ── depending on which group lens you use, different faces of the same type emerge. The keys are "how it is formed and how it is classified" and "which traits it shares and which relations it contains." All groups on this page correspond to the "Groups" menu at the top of the site.

How Groups Are Formed ── Tetratomies and Octatomies

In classical Socionics (Model A, 16 types), combining three independent Reinin dichotomies divides the 16 types into four. This is called a tetratomy (4-way division), and there are exactly 35 possible tetratomies (R1–R35).

In Model K (32 types), since the Q/D axis is added, the number of divisions changes even for the same combination of Reinin axes. In some cases the classical 4-way division is preserved and one group contains 8 people (tetratomy, 4 groups × 8 people: club, stress resistance, etc.), while in others Q/D further splits each group, yielding a finer 8-way division (octatomy, 8 groups × 4 people: labyrinth, mobilization, square, business square, etc.).

Kasiukov's Three Classes

Kasiukov & Makarcheva (2011) classified tetratomies into three classes according to their relationship to intertype-relation groups. This is the ordering used in §04.

Group List ── Functional Class, Trait Axes, Classical Relation Structure, Model K Contained Relations

A full list of every group in the header menu, sorted by the three classes (and Model K rings). Functional class distinguishes psychodynamic (intertype relations themselves), trait (shared traits), and ring. The "Classical relation structure" column shows the generating subgroup under the 16-type premise; the "Model K contained relations" column shows the actual internal relations in 32 types based on each group page — the two are presented separately. Comfort levels and group sizes follow the definitions on each group page.

The division coincides with the orbits of a relation group, and each class is closed under intertype relations. However, in Model K (32 types), the Q/D axis splits groups into 4-person or 8-person versions, and the internal relations also appear under different names than in classical 16 types (Model A).

The classes are orbits but the relation group differs per class (Reinin's "homogeneous" groups). Square and Business Square form a pair on the same Square page.

Groups bound only by shared traits. They are not closed under intertype relations, so they have no classical relation structure.

The classical Request Ring R32 and Supervision Ring R33, branched by Model K according to whether the regime (Democratic/Aristocratic) is shared or crossed.

The "Meaning of Shared Traits" and "Group Effect" for Each Group

The list above shows the axis names and contained relation structure. The table below summarizes in one phrase what the shared traits mean for each group (for trait-type groups) or what happens when they gather as a group (for psychodynamic-type and ring-type groups).

Ring Branching ── Model K Branches the Two Classical Rings

In the classical system there are two "rings" ── the Request Ring (R32 · заказ) and the Supervision Ring (R33 · ревизия). Model K branches these by whether the regime (Democratic/Aristocratic) is shared or crossed.

The within-regime pair (Benefactor Ring + Mentor Ring) = Succession Ring SR gently transmits via benefaction and mentor-disciple (66.7–71.4). The regime-crossing pair (Order Ring + Supervision Ring) = Social Progress Ring SPR carries the tension of advancing the era across Democratic ↔ Aristocratic (33.3–42.9). The Succession Ring consists of 16 lines = 4 basic ones (Heritage / Renaissance / Dynasty / Canon). Reading Request Ring R32 itself in terms of energy metabolism gives Inflation Ring; reading Supervision Ring R33 in terms of thinking style gives Cognitive Style.

Functional Class ── Another Way of Reading

Even for the same group, its face changes depending on whether you read it as "what happens when we are together (psychodynamic)," "which traits are shared (trait)," or "how it connects (ring)."

Average Comfort ── A One-Dimensional Map of "Healing ⇔ Training"

The internal pairs of each group are averaged by COMFORT value (Dual, Activation, Identity, Mirror = 100 … Role, Conflict, Distance = 0), arranging the texture of each group along a single axis. Values are based on the internal relation structure on each group page. Constituent rings (BR, MR, SOR, SVR) are also included. Colors follow Kasiukov's classification (factor / orbit / non-orbit / Model K ring).

With Quadra (100) and Square / Business Square (83.3) at the top, followed by Stress Resistance, Reactor, and Succession Ring, the non-igniting Block Groups (extinguishing), Labyrinth (Mirror, Role, Conflict = 33.3), Order Ring, and Supervision Ring form the bottom.

Full 35 Tetratomy Table (R order)

A list of all 35 tetratomies in R order, following Kasiukov & Makarcheva, "Definition and Classification of Small Groups in Socionics" (2011) (corresponding to the addition table of Reinin dichotomies 15 × 14 ÷ 6 = 35). Groups with an Association page are linked; groups not on the site but named in the literature are shown as literature name; unnamed groups are marked "undefined."

Factor 11Orbit 4Non-orbit 20

※ The third dichotomy of each tetratomy is uniquely determined as the sum of the other two (Reinin addition). Square (R19 · rest) and Business Square (R13 · collaboration) are treated as a pair on the Square page. Groups with literature names but no page (e.g., the Existence-Form R10) are candidates for future pages once the definition is established.
