Order 20224.
974 conjugacy classes of subgroups.
The subgroup lattice has 430 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. #19099194 | C4 | semidirect |
| 41. C2×C4⋊Dic79 | Q8 | semidirect |
| 48. C2×C4×Dic79 | Q8 | semidirect |
| 57. C2×M16×C79 | Q8 | semidirect |
| 220. C79 | #11392 | semidirect |
| 247. C2×M16 | Dic158 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
