Order 18176.
1406 conjugacy classes of subgroups.
The subgroup lattice has 330 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 12. #17985869 | C4 | semidirect |
| 90. C42×C71 | C4⋊C4 | semidirect |
| 171. C71 | #14276 | semidirect |
| 255. C42 | Dic71⋊C4 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
