17030 conjugacy classes of subgroups; only the 1626 normal subgroups are shown.

normal subgroups only

This group has 17030 conjugacy classes of subgroups — too many to draw. Only its 1626 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) = 256

A minimal faithful permutation representation — 5 generators on 18 points:

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