604 conjugacy classes of subgroups; only the 245 normal subgroups are shown.
This group has 604 conjugacy classes of subgroups — too many to draw. Only its 245 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 |
|---|---|---|
| 6. #65275 | C2 | direct (N × H) |
| 116. C2×C5 | #400 | semidirect |
| 145. C5 | C2×#400 | semidirect |
| 161. C2 | #65275 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
