Order 20224.
990 conjugacy classes of subgroups.
The subgroup lattice has 374 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23761873 | C2 | direct (N × H) |
| 4. C2×Q8⋊(C79⋊C8) | C2 | semidirect |
| 16. Q8⋊(C79⋊C8) | C22 | semidirect |
| 183. C2×C79 | #1497 | semidirect |
| 192. C79 | C2×#1497 | semidirect |
| 369. C2 | #23761873 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
