Order 18176.
830 conjugacy classes of subgroups.
The subgroup lattice has 260 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #22588479 | C2 | direct (N × H) |
| 127. C2×C71 | #1838 | semidirect |
| 136. C71 | C2×#1838 | semidirect |
| 256. C2 | #22588479 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
