2186 conjugacy classes of subgroups; only the 85 normal subgroups are shown.

normal subgroups only

This group has 2186 conjugacy classes of subgroups — too many to draw. Only its 85 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:

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