Order 1792.
612 conjugacy classes of subgroups.
The subgroup lattice has 390 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 18. C7×#324 | C4 | semidirect |
| 120. #324 | Dic7 | semidirect |
| 148. C2×C4×C7 | #106 | semidirect |
| 342. C2×C4 | #6391 | semidirect |
| 346. C7 | #8857 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
