Order 288.
90 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C2×Dic18 | C2 | semidirect |
| 3. #3674 | C2 | semidirect |
| 4. #3672 | C2 | semidirect |
| 5. #3667 | C2 | semidirect |
| 51. C9 | #137 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
