Order 18688.
1774 conjugacy classes of subgroups.
The subgroup lattice has 298 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 13. #17988433 | C4 | semidirect |
| 64. C4×Dic73 | C4⋊C4 | semidirect |
| 86. C42×C73 | C4⋊C4 | semidirect |
| 155. C73 | #13856 | semidirect |
| 235. C42 | #11924007 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
