144 conjugacy classes of subgroups; only the 44 normal subgroups are shown.
This group has 144 conjugacy classes of subgroups — too many to draw. Only its 44 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
| transitive degree | μt(G) = 2070 |
2100 conjugacy classes. The character table is too large to display.
