Since a while, there are infinite polynomial rings in Sage. OK, the generators of an infinite polynomial ring do not return *symbolic* variables, but they do return indexed polynomial variables. sage: R.<x,y> = InfinitePolynomialRing(QQ) sage: x[2]*y[1]+x[5]*y[3] y3*x5 + y1*x2 Note that there is #7580 with a positive review, that massively improves the code. I hope it will be merged soon...
