Order 20224.
1094 conjugacy classes of subgroups.
The subgroup lattice has 480 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 28. #400×C79 | C4 | semidirect |
| 249. C79 | #14612 | semidirect |
| 255. #400 | Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
