Order 20224.
730 conjugacy classes of subgroups.
The subgroup lattice has 414 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 17. #19098288 | C4 | semidirect |
| 30. C2×Dic79⋊C4 | C8 | semidirect |
| 39. C2×C4×Dic79 | C8 | semidirect |
| 155. C2×Dic79 | C4×C8 | semidirect |
| 194. Dic79 | #324 | semidirect |
| 212. C79 | C4×#324 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
