Order 16256.
320 conjugacy classes of subgroups.
The subgroup lattice has 182 nodes — too large to display as a diagram.
| subgroup | G/H | |
|---|---|---|
| center, socle, prime radical | C22×C127 | C22×D4 |
| commutator, Frattini, cosocle | C2×C4 | C24×C127 |
| LCS | G ▷ C2×C4 ▷ C2 ▷ C1 | |
| UCS | C1 ◁ C22×C127 ◁ C4×Q8×C127 ◁ G | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
