424 conjugacy classes of subgroups; only the 130 normal subgroups are shown.

normal subgroups only

This group has 424 conjugacy classes of subgroups — too many to draw. Only its 130 normal subgroups are shown.

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

minimal degreeμ(G) = 32
transitive degreeμt(G) = 960

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

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