150 conjugacy classes of subgroups; only the 10 normal subgroups are shown.

normal subgroups only

This group has 150 conjugacy classes of subgroups — too many to draw. Only its 10 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 80
transitive degreeμt(G) = 80

A minimal faithful permutation representation — 2 generators on 80 points:
