404 conjugacy classes of subgroups; only the 65 normal subgroups are shown.

normal subgroups only

This group has 404 conjugacy classes of subgroups — too many to draw. Only its 65 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) = 180

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

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

Polycyclic presentation:
