We want the mapping to be bijective (a one-to-one mapping without “holes”). The factoradic system is what we need, as explained via the following table. The digit ranges reflect the rules of the Lehmer code. This manual page documents briefly the mlucas command. mlucas is an open-source (and free/libre) program for performing Lucas-Lehmer test on prime-exponent Mersenne numbers, that is, integers of the form 2 ^ p - 1, with prime exponent p. In short, everything you need to search for world-record Mersenne primes!In mathematics, the Lucas–Lehmer–Riesel test is a primality test for numbers of the form N = k ⋅ 2 n − 1 ( Riesel numbers) with odd k < 2 n. The test was developed by Hans Riesel and it is based on the Lucas–Lehmer primality test. It is the fastest deterministic algorithm known for numbers of that form.
