[sage-support] Order of Variables of Polynomial Matters

I saw this behavior sage: R1. = QQ[] sage: R2. = QQ[] # Rearrange variables of R1 sage: R1 Multivariate Polynomial Ring in x, y, z over Rational Field sage: R2 Multivariate Polynomial Ring in z, x, y over Rational Field sage: R1 is R2 False sage: print(R1.gens(), R1.variable_names()) (x, y, z) ('

I was looking into this issue This throws error: - sage: R1. = QQ[] sage: p = (x^2 - y^2) * (x + y + z) sage: S = QQ['z']['x,y'] sage: try:
