Order 20224.
2018 conjugacy classes of subgroups.
The subgroup lattice has 248 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. #19099041 | C4 | semidirect |
| 10. C2×Q8×Dic79 | C4 | semidirect |
| 16. #519×C79 | C4 | semidirect |
| 128. C79 | #20355 | semidirect |
| 135. #519 | Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
