1422789 conjugacy classes of subgroups; only the 147 normal subgroups are shown.

normal subgroups only

This group has 1422789 conjugacy classes of subgroups — too many to draw. Only its 147 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) = 24

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

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