9999 conjugacy classes of subgroups; only the 3695 normal subgroups are shown.

normal subgroups only

This group has 9999 conjugacy classes of subgroups — too many to draw. Only its 3695 normal subgroups are shown.

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

minimal degree	μ(G) = 14
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 14 points:

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