1427 conjugacy classes of subgroups; only the 52 normal subgroups are shown.

normal subgroups only

This group has 1427 conjugacy classes of subgroups — too many to draw. Only its 52 normal subgroups are shown.

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