3394 conjugacy classes of subgroups; only the 59 normal subgroups are shown.

normal subgroups only

This group has 3394 conjugacy classes of subgroups — too many to draw. Only its 59 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:

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