1109 conjugacy classes of subgroups; only the 77 normal subgroups are shown.

normal subgroups only

This group has 1109 conjugacy classes of subgroups — too many to draw. Only its 77 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) = 144

A minimal faithful permutation representation — 2 generators on 24 points:

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