4624 conjugacy classes of subgroups; only the 90 normal subgroups are shown.

normal subgroups only

This group has 4624 conjugacy classes of subgroups — too many to draw. Only its 90 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 3 generators on 32 points:

(2,7)(8,20)(9,24)(10,17)(11,22)(14,28)(21,25)(23,31)(26,32)(27,29);(2,8)(7,20)(9,23)(10,14)(11,22)(12,18)(17,28)(21,32)(24,31)(25,26);(1,2,3,9)(4,14,11,26,16,8,22,23)(5,17,18,24)(6,10,13,25)(7,12,21,19)(15,28,29,32,30,20,27,31)
