Magma Computer Algebra System vs PARI/GP

Magma Computer Algebra System has no write-up on Specifiction yet; its figures are above.

PARI/GP is a free, open-source computer algebra system designed for fast number-theory computations. Its functions cover factorization, algebraic number theory, elliptic curves, modular forms, L-functions, matrices, polynomials, power series, algebraic numbers, and transcendental functions. PARI is available as a C library; gp is an interactive shell, and GP is its scripting language. The gp2c compiler translates a subset of GP scripts to C and can make compiled scripts three or four times faster. The official site offers a browser-based GP interface for expressions, variables, and function definitions, though its stated speed is approximately 15% of native speed. Xeus-GP is a Xeus-based Jupyter kernel. Optional packages are distributed separately because they use substantial disk space and are expected to be unnecessary for most users. The project provides guides, reference manuals, tutorials, quick reference cards, and downloadable manuals. The project directs users to a mailing list for help and a bug tracker for reports and feature requests. It is licensed under GNU GPL version 2 or later.
