Transitive groups of degree up to 15

When G acts on a (finite) set, the set is a disjoint union of orbits, the transitive G-sets. There is a natural bijection

 {transitive G-sets up to ≅} ↔ {subgroups of G up to conjugacy} X ↦ stabiliser of a point G/H ↤ H

Transitive G-sets on which G acts faithfully correspond to subgroups H with trivial core (or core-free), that is those where the intersection of H with all of its conjugates is trivial; equivalently, H contains no non-trivial normal subgroup of G. In this case G can be viewed as a transitive subgroup of Sn for n=(G:H), the index of H in G, called the transitive degree. Conversely, all transitive subgroups of Sn arise in this way. The transitive group database in GAP and Magma contains all transitive subgroups of Sn up to conjugacy for n≤31, numbered nTi (or Tn,i).

The table below lists all transitive groups with n≤15. See also the full table with n≤31 and the smallest transitive degree table (n≤120).
