266 conjugacy classes of subgroups; only the 64 normal subgroups are shown.
This group has 266 conjugacy classes of subgroups — too many to draw. Only its 64 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
2871 conjugacy classes. The character table is too large to display.
