622 conjugacy classes of subgroups; only the 80 normal subgroups are shown.

normal subgroups only

This group has 622 conjugacy classes of subgroups — too many to draw. Only its 80 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) = 108

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

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