426 conjugacy classes of subgroups; only the 194 normal subgroups are shown.

normal subgroups only

This group has 426 conjugacy classes of subgroups — too many to draw. Only its 194 normal subgroups are shown.

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

minimal degree	μ(G) = 15
transitive degree	μ_t(G) = 160

A minimal faithful permutation representation — 4 generators on 15 points:

(1,2)(11,12,13,14,15);(4,6)(8,10);(1,2)(7,8,9,10);(1,2)(3,4)(5,6)
