186 conjugacy classes of subgroups; only the 52 normal subgroups are shown.
This group has 186 conjugacy classes of subgroups — too many to draw. Only its 52 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 |
|---|---|---|
| 1. C2×#19099583 | C2 | semidirect |
| 2. #23778840 | C2 | direct (N × H) |
| 5. #19099583 | C22 | semidirect |
| 47. C2×C317 | #100 | semidirect |
| 50. C317 | C2×#100 | semidirect |
| 99. C2 | #23778840 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
