Order 15616.
750 conjugacy classes of subgroups.
The subgroup lattice has 614 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #21460909 | C2 | direct (N × H) |
| 307. C2×C61 | #1392 | semidirect |
| 335. C61 | C2×#1392 | semidirect |
| 611. C2 | #21460909 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
