Order 768.
670 conjugacy classes of subgroups.
The subgroup lattice has 256 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 12. C3×#501 | C4 | semidirect |
| 61. #815 | Q8 | semidirect |
| 63. C8×Dic3 | Q8 | semidirect |
| 70. #501 | Dic3 | semidirect |
| 250. C3 | #21736 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
