369 conjugacy classes of subgroups; only the 10 normal subgroups are shown.

normal subgroups only

This group has 369 conjugacy classes of subgroups — too many to draw. Only its 10 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 — 2 generators on 23 points:

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