pipeDreamsNonReduced -- computes the set of all pipe dreams corresponding to a permutation



Given a permutation in one line notation, finds the set of pipe dreams. Each element of the output is a square array containing "+" and "/" symbols. The "+" symbols are interpreted as crossing tiles and the "/" are interpreted as bump tiles. Starting on the left edge, the path starting at row $i$ will end at column $w_i$. This function returns all pipe dreams of w, including those containing pairs of pipes that cross more than once.

i1 : w = {2,1,4,3,6,5};
i2 : (pipeDreamsNonReduced w)_1

o2 = +/+/+/

o2 : PipeDream
