947 conjugacy classes of subgroups; only the 134 normal subgroups are shown.
This group has 947 conjugacy classes of subgroups — too many to draw. Only its 134 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
