Maximal sets of mutually orthogonal frequency squares and Doehlert-Klee designs

Abstract A binary frequency square of type $$(n;\lambda _0,\lambda _1)$$ ( n ; λ 0 , λ 1 ) is a (0, 1)-matrix of order n with $$\lambda _0$$ λ 0 zeros and $$\lambda _1$$ λ 1 ones in each row and in each column. Two such squares are orthogonal if there are exactly $$\lambda _1^2$$...
