610 conjugacy classes of subgroups; only the 28 normal subgroups are shown.

normal subgroups only

This group has 610 conjugacy classes of subgroups — too many to draw. Only its 28 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) = 126

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

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