## Abstract

Fuchs asked: For which integer partitions g_{1} +· · · g_{n} = N does there exist a latin square of side N having n subsquares of sides g_{1}, …,g_{n} having no rows, columns, or symbols in common? Only when at most two distinct integer parts are used is the answer known completely; in general even the necessary conditions are elusive. Two conjectures giving plausible sufficient conditions are advanced. The first asserts than whenever the largest three integer parts are the same, such a latin square always exists. The second asserts that whenever the largest part is no larger than n − 2 times the smallest, such a latin square always exists. Partial results on both are established.
