729 conjugacy classes of subgroups; only the 29 normal subgroups are shown.

normal subgroups only

This group has 729 conjugacy classes of subgroups — too many to draw. Only its 29 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) = 64

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

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