from sage.rings.polynomial.polynomial_ring_constructor import PolynomialRing from sage.rings.finite_rings.finite_field_constructor import GF F = GF(5) R = PolynomialRing(F, 'x')This code creates a polynomial ring `R` over the finite field with 5 elements (`GF(5)`), with variable `x`. These code examples use the SageMath package library, which is a popular open-source mathematics software that provides a variety of mathematical tools for research and education.
