348 conjugacy classes of subgroups; only the 159 normal subgroups are shown.
This group has 348 conjugacy classes of subgroups — too many to draw. Only its 159 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
