Order 15616.
830 conjugacy classes of subgroups.
The subgroup lattice has 220 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 98. C4×C61 | #499 | semidirect |
| 132. C61 | #33311 | semidirect |
| 211. C4 | #16840163 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
