Static symmetry group.
This class represents a symmetry group that is known and resolved completely at compile time. Ideally, no run-time penalty is incurred compared to the manual unrolling of the symmetry.
CAUTION:
Do not use this class directly for large symmetry groups. The compiler may run into a limit, or segfault or in the very least will take a very, very, very long time to compile the code. Use the SGroup class instead if you want a static group. That class contains logic that will automatically select the DynamicSGroup class instead if the symmetry group becomes too large. (In that case, unrolling may not even be beneficial.)
