Order 1728.
890 conjugacy classes of subgroups.
The subgroup lattice has 240 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |

| 5. #10588891 | C3 | direct (N × H) |
| 8. C22×C3×C4×C9 | C4 | semidirect |
| 18. C9⋊#95 | C2×C3 | semidirect |
| 42. C22×C4×C9 | C3×C4 | semidirect |
| 100. C22×C3×C4 | Dic9 | semidirect |
| 133. C3×C9 | #381 | semidirect |
