3368 conjugacy classes of subgroups; only the 82 normal subgroups are shown.

normal subgroups only

This group has 3368 conjugacy classes of subgroups — too many to draw. Only its 82 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 112

A minimal faithful permutation representation — 3 generators on 23 points:

(1,2,3,4,5,6,7)(9,20,23,14,15,22)(10,21,13,18,16,17)(11,19,12);(9,17)(10,18)(13,14)(15,20);(8,21,12,16)(9,18,13,15)(10,14,20,17)(11,23,19,22)
