Order 18176.
1854 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 |
|---|---|---|
| 11. #17985869 | C4 | semidirect |
| 66. C42×C71 | C4⋊C4 | semidirect |
| 108. C4×C71 | #389 | semidirect |
| 125. C71 | #14712 | semidirect |
| 186. C42 | Dic71⋊C4 | semidirect |
| 231. C4 | #17985895 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
