PetscDualSpaceGetSymmetries

Returns a description of the symmetries of this basis

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceGetSymmetries(PetscDualSpace sp, const PetscInt ****perms, const PetscScalar ****flips)

Not collective

sp -the PetscDualSpace object

	perms	- Permutations of the interior degrees of freedom, parameterized by the point orientation
	flips	- Sign reversal of the interior degrees of freedom, parameterized by the point orientation

Note: The permutation and flip arrays are organized in the following way

perms[p][ornt][dof # on point] = new local dof #

flips[p][ornt][dof # on point] = reversal or not
