780 conjugacy classes of subgroups; only the 162 normal subgroups are shown.
This group has 780 conjugacy classes of subgroups — too many to draw. Only its 162 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

A minimal faithful permutation representation — 3 generators on 19 points:
