Order 18688.
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. #22610070 | C2 | direct (N × H) |
| 127. C2×C73 | #1838 | semidirect |
| 136. C73 | C2×#1838 | semidirect |
| 256. C2 | #22610070 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
