| sys | - the section symmetries | |
| stratum | - the stratum value in the label that we are assigning symmetries for | |
| size | - the number of dofs for points in the stratum of the label | |
| minOrient | - the smallest orientation for a point in this stratum | |
| maxOrient | - one greater than the largest orientation for a ppoint in this stratum (i.e., orientations are in the range [minOrient, maxOrient)) | |
| mode | - how sym should copy the perms and rots arrays | |
| perms | - NULL if there are no permutations, or (maxOrient - minOrient) permutations, one for each orientation. A NULL permutation is the identity + rots - NULL if there are no rotations, or (maxOrient - minOrient) sets of rotations, one for each orientation. A NULL set of orientations is the identity |
