coefficientRing(SchurRing) -- Coefficient ring of a Schur ring

Synopsis

Description

Given a Schur ring S, the function returns its coefficient ring.

i1 : S = schurRing(ZZ[x],s,4);
 
i2 : coefficientRing S

o2 = ZZ[x]

o2 : PolynomialRing
 
i3 : A = schurRing(QQ,a,3);
 
i4 : B = schurRing(A,b,2);
 
i5 : coefficientRing B

o5 = A

o5 : SchurRing
