Order 512.
1666 conjugacy classes of subgroups.
The subgroup lattice has 367 nodes — too large to display as a diagram.

Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #19209 | C2 | direct (N × H) |
| 5. C2×#1696 | C2 | semidirect |
| 6. C2×#1676 | C2 | semidirect |
