Order 18688.
1550 conjugacy classes of subgroups.
The subgroup lattice has 278 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 14. #17988433 | C4 | semidirect |
| 60. C4×Dic73 | C4⋊C4 | semidirect |
| 80. C42×C73 | C4⋊C4 | semidirect |
| 145. C73 | #14354 | semidirect |
| 219. C42 | #11924007 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
