PETSc version v3.15.4-900-g21e6d802fb
Split the integers [0, ..., n - 1] into two complementary ordered subsets, the first subset of size k and being the jth subset of that size in lexicographic order.
|n ||- a non-negative integer (see note about limits below)
|k ||- an integer in [0, n]
|j ||- an index in [0, n choose k)
|perm ||- the jth subset of size k of the integers [0, ..., n - 1], followed by its complementary set.
|isOdd ||- if not NULL, return whether perm is an even or odd permutation.
Note: this is limited by arguments such that n choose k can be represented by PetscInt
