715 conjugacy classes of subgroups; only the 189 normal subgroups are shown.

normal subgroups only

This group has 715 conjugacy classes of subgroups — too many to draw. Only its 189 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) = 288

A minimal faithful permutation representation — 3 generators on 21 points:

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