234 conjugacy classes of subgroups; only the 87 normal subgroups are shown.
This group has 234 conjugacy classes of subgroups — too many to draw. Only its 87 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×Dic311⋊C4 | C2 | semidirect |
| 4. C311⋊#95 | C2 | semidirect |
| 11. C22⋊Dic311 | C4 | semidirect |
| 22. C2×Dic311 | C2×C4 | semidirect |

By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
