Order 17536.
400 conjugacy classes of subgroups.
The subgroup lattice has 146 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #22577534 | C2 | direct (N × H) |
| 23. C2×#11764040 | Q8 | semidirect |
| 42. #11764040 | C2×Q8 | semidirect |
| 68. C2×C137 | #446 | semidirect |
| 72. C137 | C2×#446 | semidirect |
| 141. C2 | #22577534 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
