570 conjugacy classes of subgroups; only the 66 normal subgroups are shown.

normal subgroups only

This group has 570 conjugacy classes of subgroups — too many to draw. Only its 66 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) = 120

A minimal faithful permutation representation — 2 generators on 18 points:

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

Conjugacy classes & character table
