Order 4448.
76 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. Dic139⋊C4 | C2 | semidirect |
| 4. C4×Dic139 | C2 | semidirect |
| 6. C2×Dic139 | C4 | semidirect |
| 22. C139 | #117 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
