624 conjugacy classes of subgroups; only the 269 normal subgroups are shown.
This group has 624 conjugacy classes of subgroups — too many to draw. Only its 269 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.

| 2. #23781532 | C2 | direct (N × H) |
| 10. C2×C4×Dic163 | C4 | semidirect |

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