PARI is a widely used computer algebra system designed for fast computations in number theory (factorizations, algebraic number theory, elliptic curves...), but also contains a large number of other useful functions to compute with mathematical entities such as matrices, polynomials, power series, algebraic numbers, etc., and a lot of transcendental functions. The extra data is avaialable through use flag: * elldata is PARI/GP version of J. E. Cremona Elliptic Curve Data, needed by ellsearch and ellidentify. * galdata is needed by polgalois to compute Galois group in degrees 8 through 11. * seadata is needed by ellap for large primes. * nftables is a repackaging of the historical megrez number field tables (errors fixed, 1/10th the size, easier to use).
