Order 20224.
1006 conjugacy classes of subgroups.
The subgroup lattice has 282 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23763529 | C2 | direct (N × H) |
| 10. C2×C8×Dic79 | C4 | semidirect |
| 35. C8×Dic79 | C2×C4 | semidirect |
| 135. C2×C79 | #1835 | semidirect |
| 147. C79 | C2×#1835 | semidirect |
| 275. C2 | #23763529 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
