Primitive Pythagorean Triples on the vine

All Primitive Pythagorean Triples can be shown to belong to a vine-like structure, with a ‘root’, a horizontal ‘main stem’, and binary branching sequences which are seeded from the main stem triples and every other triple below it.

From Euclid to Fermat

Primitive Pythagorean Triples, or PPT’s, are non-trivial integer solutions to the Pythagorean equation z2 = x2 + y2 where we assume that 0<x<y<z, and that x, y and z are co-prime. Euclid’s formulae allow PPT’s to be generated using 2 (positive integer) parameters, usually denoted by m and n. The PPT’s (usually) take the form […]
