S = oscRing G
S = oscRing n
This function returns a polynomial ring in $2n$ variables representing the cosine and the sine of $n$ angles. Inputting a number assumes that the vertices are labeled $0, \ldots, n$.

If one gives a graph with Reduced => true, then the number of angles considered is one less than the number of vertices of the graph.
