Order 1980.
36 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. C5×C9×C11 | C4 | semidirect |
| 8. C9⋊AGL(1,𝔽5) | C11 | direct (N × H) |
| 12. C9×C11 | AGL(1,𝔽5) | semidirect |
| 16. C5×C11 | Dic9 | semidirect |
| 17. C5×C9 | C4×C11 | semidirect |
| 27. C11 | C9⋊AGL(1,𝔽5) | direct (N × H) |
| 29. C9 | C11×AGL(1,𝔽5) | semidirect |
| 31. C5 | C11×Dic9 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
