1032 conjugacy classes of subgroups; only the 60 normal subgroups are shown.

normal subgroups only

This group has 1032 conjugacy classes of subgroups — too many to draw. Only its 60 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) = 60

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

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