979 conjugacy classes of subgroups; only the 37 normal subgroups are shown.

normal subgroups only

This group has 979 conjugacy classes of subgroups — too many to draw. Only its 37 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) = 64

A minimal faithful permutation representation — 3 generators on 24 points:

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