Order 18176.
2814 conjugacy classes of subgroups.
The subgroup lattice has 352 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #22591631 | C2 | direct (N × H) |
| 52. C2×C4×Dic71 | Q8 | semidirect |
| 95. C4×Dic71 | C2×Q8 | semidirect |
| 171. C2×C71 | #2399 | semidirect |
| 185. C71 | C2×#2399 | semidirect |
| 346. C2 | #22591631 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
