482 conjugacy classes of subgroups; only the 51 normal subgroups are shown.

normal subgroups only

This group has 482 conjugacy classes of subgroups — too many to draw. Only its 51 normal subgroups are shown.

Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

minimal degree	μ(G) = 18
transitive degree	μ_t(G) = 180

A minimal faithful permutation representation — 2 generators on 18 points:

(1,4,3)(5,6,8,9,7)(11,15,16,13,14,18)(12,17);(2,4)(6,7)(8,9)(10,16,13,12,14,15,17,11,18)

maximal subgroup of	D₅×S₄×AGL(1,ℤ/9)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((1,4,3)(5,6,8,9,7)(11,15,16,13,14,18)(12,17), (2,4)(6,7)(8,9)(10,16,13,12,14,15,17,11,18));
