3876 conjugacy classes of subgroups; only the 438 normal subgroups are shown.

normal subgroups only

This group has 3876 conjugacy classes of subgroups — too many to draw. Only its 438 normal subgroups are shown.

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

minimal degree	μ(G) = 21
transitive degree	μ_t(G) = 320

A minimal faithful permutation representation — 4 generators on 21 points:

(1,2,3,4,5)(6,7)(8,9)(10,11)(12,13)(15,18)(16,20)(19,21);(14,15,17,19)(16,21,20,18);(7,9);(11,13)
