540 conjugacy classes of subgroups; only the 84 normal subgroups are shown.

normal subgroups only

This group has 540 conjugacy classes of subgroups — too many to draw. Only its 84 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 112

A minimal faithful permutation representation — 3 generators on 23 points:

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