### Abstract

In this paper we investigate equations featuring sums of consecutive square integers, such as , and . In general, for a sum of consecutive square integers, , there is a distinct set of consecutive squares, , to which these are equal. We present a bootstrap method for constructing these equations, which yields solutions comprising an infinite two-dimensional array. We apply a similar method to constructing consecutive square sum equations involving terms on the left, and terms on the right, formed from two distinct sets of consecutive squares separated one term to the left of the equals sign, such as .
