Order 20224.
660 conjugacy classes of subgroups.
The subgroup lattice has 340 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 17. #398×C79 | C4 | semidirect |
| 175. C79 | #9027 | semidirect |
| 182. #398 | Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
