3648 conjugacy classes of subgroups; only the 155 normal subgroups are shown.

normal subgroups only

This group has 3648 conjugacy classes of subgroups — too many to draw. Only its 155 normal subgroups are shown.

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

minimal degreeμ(G) = 17
transitive degreeμt(G) = 84

A minimal faithful permutation representation — 3 generators on 17 points:

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