Order 20224.
1254 conjugacy classes of subgroups.
The subgroup lattice has 368 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 20. #391×C79 | C4 | semidirect |
| 29. C2×C4⋊Dic79 | Q8 | semidirect |
| 190. C79 | #14471 | semidirect |
| 197. #391 | Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
