Square prism
Notes:
- Faces and corners are referred to using compass directions, with north oriented in the direction of positive y-axis.
| Symmetry option | Equivalent surfaces | Equivalent corners | Symmetry axis |
|---|---|---|---|
| 0, NO, NONE | - | - | - |
| 1, ALL | W-S-E-N | NW-NE-SE-SW | - |
| 2, NS, SN | N-S | NW-SW, NE-SE | from side E to side W |
| 3, NESW, SWNE | N-E, S-W | SE-NW | from corner NE to corner SW |

| 5, NWSE, SWNE | N-W, S-E | NE-SW | 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.
| Symmetry option | Equivalent surfaces | Equivalent corners | Symmetry axis | Note |
|---|---|---|---|---|
| 0, NO, NONE | - | - | - | |
| 1, ALL, 30 | 1-2-3-4-5-6 | 1-2-3-4-5-6 | - | useful for 30 degree periodic symmetric hexagonal lattices |
| 2 | 2-6, 3-5 | 1-4, 2-3, 5-6 | from side 1 to side 4 | |
| 3 | 1-2, 3-6, 4-5 | 1-3, 4-6 | from corner 2 to corner 5 | |
| 4 | 1-3, 4-6 | 1-2, 3-6, 4-5 | from side 2 to side 5 | |
| 5 | 1-4, 2-3, 5-6 | 2-6, 3-5 | from corner 1 to corner 4 | |
| 6 | 2-4, 1-5 | 1-6, 2-5, 3-4 | from side 3 to side 6 | |
| 7 | 1-6, 2-5, 3-4 | 1-5, 2-4 | from corner 3 to corner 6 | |
| 8, 60 | 1-2-3-4-5-6 | 1-3-5, 2-4-6 | - | useful for 60 degree periodic symmetric hexagonal lattices |
| 9, 120 | 1-3-5, 2-4-6 | 1-3-5, 2-4-6 | - | useful for 120 degree periodic symmetric hexagonal lattices |
