404 conjugacy classes of subgroups; only the 170 normal subgroups are shown.

normal subgroups only

This group has 404 conjugacy classes of subgroups — too many to draw. Only its 170 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 960

A minimal faithful permutation representation — 3 generators on 40 points:
