234 conjugacy classes of subgroups; only the 32 normal subgroups are shown.

normal subgroups only

This group has 234 conjugacy classes of subgroups — too many to draw. Only its 32 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 168

A minimal faithful permutation representation — 3 generators on 18 points:

(1,7,6,3,4,2,8,5)(10,13,14,11,12,15)(17,18);(2,6,3)(5,7,8)(9,10,12,15,14,13,11);(2,6,3)(5,7,8)(16,17,18)

Polycyclic presentation:
