The maximum number of mutually orthogonal Sudoku Latin squares (MOSLS) of orderis. In this paper, we construct for,qa prime power, a set ofMOSLS of orderthat cannot be extended to a set ofMOSLS. This contrasts to the theory of ordinary Latin squares of ordern, where each set ofmutually orthogonal Latin Squares (MOLS) can be extended to a set ofMOLS (which is best possible). For this proof, we construct a particular maximal partial spread of sizeinand use a connection between Sudoku Latin squares and projective geometry, established by Bailey, Cameron and Connelly.
