Order 1792.
874 conjugacy classes of subgroups.
The subgroup lattice has 328 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. C7×Q82 | C4 | semidirect |
| 10. C7×#557 | C4 | semidirect |
| 120. Q82 | Dic7 | semidirect |
| 122. #557 | Dic7 | semidirect |
| 305. C7 | #17632 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
