Order 16256.
1048 conjugacy classes of subgroups.
The subgroup lattice has 196 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #22550601 | C2 | direct (N × H) |
| 35. C2×Dic254 | Q8 | semidirect |
| 62. Dic254 | C2×Q8 | semidirect |
| 93. C2×C127 | #557 | semidirect |
| 98. C127 | C2×#557 | semidirect |
| 191. C2 | #22550601 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
