Order 1944.
246 conjugacy classes of subgroups; only the 99 normal subgroups are shown.
This group has 246 conjugacy classes of subgroups — too many to draw. Only its 99 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 5. Dic18⋊C9 | C3 | semidirect |

| 19. C9×3−1+2 | Q8 | semidirect |
| 22. 3−1+2⋊Q8 | C9 | direct (N × H) |
| 53. C9⋊C9 | C3×Q8 | semidirect |
| 56. C92 | C3×Q8 | semidirect |
| 62. Dic18 | C3×C9 | semidirect |

By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
