Babylonian spiral

Discussion thread for Babylonian spiral.

The statement currently wrongfully indicates:

xᵢ² + yᵢ² = nᵢ² > nᵢ₋₁² where xᵢ, yᵢ and nᵢ are non-negative integers

but actually the nᵢ’s defined as such are not necessarily integers. More likely, they should simply not be squared here: This problem is not related to Pythagorean triples.
