642 conjugacy classes of subgroups; only the 111 normal subgroups are shown.

normal subgroups only

This group has 642 conjugacy classes of subgroups — too many to draw. Only its 111 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) = 32

A minimal faithful permutation representation — 4 generators on 18 points:

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