Square prism
Notes:
- Faces and corners are referred to using compass directions, with north oriented in the direction of positive y-axis.
- Options 2-5 can be understood as mirror symmetries.
- Symmetry options of sign moments were added in version 2.1.32.
- Symmetry option 6 were added in version 2.1.32.
| Symmetry option | Equivalent surfaces | Equivalent corners | Equivalent sign moments | Zero sign moments | Symmetry axis |
|---|---|---|---|---|---|
| 0, NO, NONE | - | - | - | - | - |
| 1, FULL | W-S-E-N | NW-NE-SE-SW | - | N, W, S, E | - |
| 2, NS, SN | N-S | NW-SW, NE-SE | N-S | W, E | from side E to side W |
| 3, NESW, SWNE | N-E, S-W | SE-NW | N-E, S-W | - | from corner NE to corner SW |
| 4, EW, WE | E-W | SW-SE, NW-NE | E-W | N, S | from side N to side S |
| 5, NWSE, SENW | N-W, S-E | NE-SW | N-W, S-E | - | from corner NW to SE |

Hexagonal prisms
Notes:
- The face and corner directions are listed in Assembly discontinuity factors.
- The corner symmetries have been wrong prior to version 2.1.32. The list below corresponds to the correct values used since version 2.1.32.
- Symmetry options 8 and 9 were added in version 2.1.32.
- Options 2-7 can be understood as mirror symmetries.
- Sign moments are only scored for X-type infinite/truncated hexagonal prisms (not Y-type).
