|This article is about a function from ApCoCoA-2.|
Returns the superring of a given subalgebra.
SB.GetRing(S: TAGGED("$apcocoa/sagbi.Subalgebra")): RING
This function returns the superring of a given subalgebra S, i.e. the ring R which S is a subalgebra of.
@param S A subalgebra
@return The superring of S
Use R ::= QQ[x,y,z]; S := SB.Subalgebra(R,[x^2,y+z]); PrintLn SB.GetRing(S); -- RingWithID(1217, "QQ[x,y,z]")
