104 conjugacy classes of subgroups; only the 50 normal subgroups are shown.

normal subgroups only

This group has 104 conjugacy classes of subgroups — too many to draw. Only its 50 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) = 80

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

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