Order 512.
994 conjugacy classes of subgroups.
The subgroup lattice has 378 nodes — too large to display as a diagram.
| subgroup | G/H | |
|---|---|---|
| center, socle | C23 | C2×#121 |
| commutator, Frattini, cosocle | C2×C42 | C24 |

Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. C2×#1690 | C2 | semidirect |
| 5. #9228 | C2 | semidirect |
