Order 18176.
1942 conjugacy classes of subgroups.
The subgroup lattice has 320 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 12. #17985918 | C4 | direct (N × H) |
| 36. C2×C4×Dic71 | Q8 | semidirect |
| 132. C2×Dic71 | C4×Q8 | semidirect |
| 147. C4×C71 | #395 | semidirect |
| 167. C71 | C4×#395 | semidirect |
| 311. C4 | #17985918 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
