2437 conjugacy classes of subgroups; only the 79 normal subgroups are shown.

normal subgroups only

This group has 2437 conjugacy classes of subgroups — too many to draw. Only its 79 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 — 3 generators on 24 points:

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