§ 27.22. Software
In this section we provide links to the known sources of software for factorization and primality testing, as well as additional Web-based resources for information on these topics.

Maple (). isprime combines a strong pseudoprime test and a Lucas pseudoprime test. ifactor uses cfrac (§27.19) after exhausting trial division. Brent-Pollard rho, Square Forms Factorization, and ecm are available also; see §27.19.

Mathematica (). PrimeQ combines strong pseudoprime tests for the bases 2 and 3 and a Lucas pseudoprime test. No known composite numbers pass these three tests, and Bleichenbacher (1996) has shown that this combination of tests proves primality for integers below
. Provable PrimeQ
uses the Atkin-Goldwasser-Kilian-Morain Elliptic Curve Method
to prove primality. FactorInteger tries Brent-Pollard rho, Pollard
,
and then cfrac after trial division. See §27.19. ecm
is available also, and the Multiple Polynomial
Quadratic sieve is expected in a future release.For additional Mathematica routines for factorization and primality testing, including several different pseudoprime tests, see Bressoud and Wagon (2000).
