170 conjugacy classes of subgroups; only the 70 normal subgroups are shown.

normal subgroups only

This group has 170 conjugacy classes of subgroups — too many to draw. Only its 70 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) = 160

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

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