2096 conjugacy classes of subgroups; only the 69 normal subgroups are shown.

normal subgroups only

This group has 2096 conjugacy classes of subgroups — too many to draw. Only its 69 normal subgroups are shown.

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

minimal degreeμ(G) = 31
transitive degreeμt(G) = 168

A minimal faithful permutation representation — 3 generators on 31 points:

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