1016 conjugacy classes of subgroups; only the 225 normal subgroups are shown.

normal subgroups only

This group has 1016 conjugacy classes of subgroups — too many to draw. Only its 225 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 27
transitive degreeμt(G) = 384

A minimal faithful permutation representation — 3 generators on 27 points:

(1,2,3)(4,5,6,8,7,9,10,11);(5,9)(8,11)(12,14,21,19,17,22,25,20,18,23,16,26,15,24,27,13);(2,3)(5,8)(6,10)(9,11)(12,13,15,19,18,20,17,26)(14,16,22,25,23,21,24,27)

Polycyclic presentation:
