Order 20224.
462 conjugacy classes of subgroups.
The subgroup lattice has 390 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 10. #19098289 | C4 | semidirect |
| 14. #324×C79 | C4 | semidirect |
| 21. C2×C4⋊Dic79 | C8 | semidirect |
| 25. C2×C4×Dic79 | C8 | semidirect |
| 198. C79 | #7189 | semidirect |
| 209. #324 | Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
