WebTo utilize Coppersmith attack, we used SageMath's small_roots with $\beta = 0.5$ and $\epsilon$ that 2^{166} \le \frac{1}{2} n^{\beta^2 - \epsilon} We decided to use $\epsilon = 0.034$ and run the algorithm.

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. Note that ...
