Abstract

Two ways of constructing maximal sets of mutually orthogonal Latin squares are presented.The first construction uses maximal partial spreads in PG(3, 4) \ PG(3, 2) with r lines, where r ∈ {6, 7}, to construct transversal-free translation nets of order 16 and degree r + 3 and hence maximal sets of r + 1 mutually orthogonal Latin squares of order 16. Thus sets of t MAXMOLS(16) are obtained for two previously open cases, namely for t = 7 and t = 8.The second one uses the (non)existence of spreads and ovoids of hyperbolic quadrics Q+ (2m + 1, q), and yields infinite classes of q2n − 1 − 1 MAXMOLS(q2n), for n ≥ 2 and q a power of two, and for n = 2 and q a power of three.
