Compute list of AS neighbors in border of OO

Syntax

$borderbasis.ASneighbors(OO:LIST):LIST

Description

Computes the list of across-the-street neighbors in the border of OO. The input is a list of terms OO (2nd element of type POLY). The output is a list of quadruples <formula>[i,j,k,l]</formula> s.t. <formula>x_k * b_i = x_l * b_j</formula>.
