414 conjugacy classes of subgroups; only the 39 normal subgroups are shown.

normal subgroups only

This group has 414 conjugacy classes of subgroups — too many to draw. Only its 39 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 17
transitive degreeμt(G) = 108

A minimal faithful permutation representation — 2 generators on 17 points:

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