655 conjugacy classes of subgroups; only the 23 normal subgroups are shown.

normal subgroups only

This group has 655 conjugacy classes of subgroups — too many to draw. Only its 23 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:

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

Polycyclic presentation:
