NTL: A Library for doing Number Theory

NTL is a high-performance, portable C++ library providing data structures and algorithms for manipulating signed, arbitrary length integers and for vectors, matrices, and polynomials over the integers and over finite fields.

You might face a linking error with NTL in macOS using the Apple Clang compiler:

% make                               

Consolidate compiler generated dependencies of target degrees
