Order 512.
1458 conjugacy classes of subgroups.
The subgroup lattice has 372 nodes — too large to display as a diagram.
| subgroup | G/H | |
|---|---|---|
| center, socle | C23 | C23×D4 |
| commutator, Frattini, cosocle | C22×C4 | C25 |
| prime radical | C24 | C22×D4 |
| LCS | G ▷ C22×C4 ▷ C2 ▷ C1 | |
| UCS | C1 ◁ C23 ◁ #2296 ◁ G | |
| LECS | G ▷ C22×C4 ▷ C2 ▷ C1 | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |

| 2. #28000 | C2 | semidirect |
| 3. #27990 | C2 | semidirect |
| 261. C2×C8 | #125 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
