Order 1792.
738 conjugacy classes of subgroups.
The subgroup lattice has 338 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 10. C7×#391 | C4 | semidirect |
| 11. C7×#389 | C4 | semidirect |
| 104. #391 | Dic7 | semidirect |
| 105. #389 | Dic7 | semidirect |
| 302. C7 | #9144 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
