### Abstract

An integer structure (IS) of the sum (*x*^{4} + *y*^{4}) is done using the modular ring Z_{6}. This sum generated many primes and the row structure of such primes is explored. The class functions of the composite factors of this sum are also given, and these, together with the associated row functions, illustrate why it is impossible to produce an integer to the fourth power from such sums. The overall results are consistent with those previously found with IS analysis.
