Order 1344.
130 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. C7×#557 | C3 | semidirect |
| 11. #557⋊C3 | C7 | direct (N × H) |
| 14. C7×SL(2,𝔽3) | Q8 | semidirect |
| 29. #557 | C3×C7 | semidirect |
| 57. SL(2,𝔽3) | C7×Q8 | semidirect |
| 82. C7 | #557⋊C3 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
