406 conjugacy classes of subgroups; only the 55 normal subgroups are shown.

normal subgroups only

This group has 406 conjugacy classes of subgroups — too many to draw. Only its 55 normal subgroups are shown.

Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

minimal degreeμ(G) = 17
transitive degreeμt(G) = 180

A minimal faithful permutation representation — 2 generators on 17 points:
