WebDense univariate polynomials over. Z. /. n. Z. , implemented using NTL. #. This implementation is generally slower than the FLINT implementation in polynomial_zmod_flint, so we use FLINT by default when the modulus is small enough; but NTL does not require that n be int -sized, so we use it as default when n is too large for FLINT.
