546 conjugacy classes of subgroups; only the 92 normal subgroups are shown.

normal subgroups only

This group has 546 conjugacy classes of subgroups — too many to draw. Only its 92 normal subgroups are shown.

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

Presentation

minimal degree	μ(G) = 25
transitive degree	μ_t(G) = 240

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

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