616 conjugacy classes of subgroups; only the 176 normal subgroups are shown.
This group has 616 conjugacy classes of subgroups — too many to draw. Only its 176 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
2736 conjugacy classes. The character table is too large to display.
