634 conjugacy classes of subgroups; only the 54 normal subgroups are shown.

normal subgroups only

This group has 634 conjugacy classes of subgroups — too many to draw. Only its 54 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 96

A minimal faithful permutation representation — 2 generators on 16 points:

(1,2)(5,7)(8,9,13)(10,14,12)(11,15,16);(2,3)(4,5)(6,7)(9,15,14,11)(10,16,13,12)
