Order 26973.
70 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 28. #66524 | C81 | semidirect |
| 44. C37 | C9⋊C81 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
