BB.NDneighbors
Compute a list of next-door neighbors.
Syntax
BB.NDneighbors(OO:LIST):LIST
Description
Computes the list of next-door neighbors in the border of the order ideal OO. The input is a list OO of terms that specify an order ideal. The output is a list of triples <formula>[i,j,k]</formula> such that <formula>b_i = x_k * b_j</formula>.
Example
Use Q[x,y,z]; BB.NDneighbors([1,x]); [[3, 1, 1], [4, 2, 1]] -------------------------------
