136 conjugacy classes of subgroups; only the 21 normal subgroups are shown.

normal subgroups only

This group has 136 conjugacy classes of subgroups — too many to draw. Only its 21 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) = 154

A minimal faithful permutation representation — 2 generators on 25 points:

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