Hurwitz equation


Given a length k and a multiplier m, a Hurwitz equationMathworldPlanetmath for a set of integers x1,x2,,xk states that

i=1kxi2=mi=1kxi.

There is no solution to the equation if m>k. Solutions can sometimes be found for mk by starting from a k-long set of 1s. The Markov equation for the Markov numbersMathworldPlanetmath has k=m=3.
