Lagrange proved that all positive integers can be expressed as the sum of four squares. For example, 27 = 16 + 9 + 1 + 1. However, it can also be expressed as the sum of three squares (9 + 9 + 9). In contrast, while 47 = 36 + 9 + 1 + 1, it cannot be expressed as a sum of fewer than four squares.
Write a function that produces the nth member of the sequence of numbers that cannot be expressed as the sum of fewer than four non-zero squares.
