minimalPresentation(..., Variable => ...) -- specify the variable for the new isomorphic ring

Synopsis

Description

i1 : C = ZZ/101[x,y,z,u,w]/ideal(x-x^2-y,z+x*y,w^2-u^2);
i2 : minimalPresentation(C,Variable => a)

      ZZ
     ---[x, u, w]
     101
o2 = ------------
          2    2
       - u  + w

o2 : QuotientRing

Caveat

If the symbol, u is used as a variable in the original ring an error is returned.
