Order 18688.
1430 conjugacy classes of subgroups.
The subgroup lattice has 262 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #22610014 | C2 | direct (N × H) |
| 3. C2×#17988356 | C2 | semidirect |
| 9. #17988356 | C22 | semidirect |
| 128. C2×C73 | #1822 | semidirect |
| 135. C73 | C2×#1822 | semidirect |
| 258. C2 | #22610014 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
