1167 conjugacy classes of subgroups; only the 487 normal subgroups are shown.

normal subgroups only

This group has 1167 conjugacy classes of subgroups — too many to draw. Only its 487 normal subgroups are shown.

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

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 5 generators on 20 points:

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