// The Diamond is solved if and only if: |
| 546 | 546 |
// |
| 547 |
// 1) all octahedrons are rotated with the same quat |
|
| 548 |
// 2) all tetrahedrons might be also optionally rotated by a 'face neutral' pair of quats |
|
| 549 |
// (indexes of those are kept in the 'mFaceNeutralQuattIndex' table) |
|
| 550 |
// |
|
| 551 |
// Note: this works for any size, because even if layers>3 - and then there are 'face-internal' |
|
| 552 |
// octahedrons which, it would seem, can be rotated by those 'face neutral' pairs of quats - but |
|
| 553 |
// in reality no, because if they were, the octahedrons would then not fit in the lattice... |
|
| 547 |
// - all cubits are rotated by the same quat |
|
| 548 |
// - those which are internal to the side, i.e. those which have only one 'non-black' face, might |
|
| 549 |
// also be optionally rotated by one of the two quats whose axis is perpendicular to the face. |
|
| 550 |
// (including some octahedrons if numLayers>=4) |
