Description: D. J. Bernstein's collection of tools for enumerating small solutions to certain types of equal sums of like powers.
The latest published sortedsums package is explaining the algorithms used here. sortedsums is a collection of tools for enumerating small solutions to certain types of Diophantine equations. For example, there are 14519 primitive solutions (a,b,c,d) to 5a^3 + 6b^3 = 7c^3 + 8d^3 > 0 with max{|a|,|b|,|c|,|d|} <= 10000; ``cubepqrs 5 6 7 8 10000'' prints all of them in just 69 minutes on a Pentium-100.
