11620 conjugacy classes of subgroups; only the 162 normal subgroups are shown.

normal subgroups only

This group has 11620 conjugacy classes of subgroups — too many to draw. Only its 162 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) = 72

A minimal faithful permutation representation — 4 generators on 16 points:

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

Polycyclic presentation:
