1256 conjugacy classes of subgroups; only the 68 normal subgroups are shown.

normal subgroups only

This group has 1256 conjugacy classes of subgroups — too many to draw. Only its 68 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 144

A minimal faithful permutation representation — 3 generators on 25 points:

(1,6,8,4,3,2)(5,7)(10,12,19,25,14,21,13,20)(11,16,22,24,15,23,17,18);(11,15)(16,23)(17,22)(18,24);(2,3)(4,9)(5,8)(10,11)(12,18)(13,22)(14,15)(16,20)(17,19)(21,24)(23,25)
