4438 conjugacy classes of subgroups; only the 167 normal subgroups are shown.

normal subgroups only

This group has 4438 conjugacy classes of subgroups — too many to draw. Only its 167 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 4 generators on 24 points:

(1,2)(3,7)(4,8)(5,6)(9,10)(11,17)(12,15)(13,19)(14,16)(18,20)(21,23)(22,24);(1,3,7,2,5,8,4,6)(9,11,17,10,14,19,13,16)(12,18,24,23,21,22,20,15);(3,8)(4,7)(9,12,14,21)(10,15,16,23)(11,18,19,22)(13,20,17,24);(2,6)(4,7)
