260 conjugacy classes of subgroups; only the 110 normal subgroups are shown.
This group has 260 conjugacy classes of subgroups — too many to draw. Only its 110 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 33. C4⋊Dic5 | C8 | semidirect |
| 84. C4×C5 | C4⋊C8 | semidirect |
| 140. C5 | #1939 | semidirect |
| 155. C4 | #4004 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
