776 conjugacy classes of subgroups; only the 97 normal subgroups are shown.

normal subgroups only

This group has 776 conjugacy classes of subgroups — too many to draw. Only its 97 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 — 2 generators on 18 points:

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