construct/mc ortholatin

construct/mc ortholatin: a task in MathConstructOptimize-Envs-harbor (Harbor dataset). Construct a pair of orthogonal Latin squares of order 10: two 10x10 arrays X and Y with entries in 0..9 such that every row and every column of X is a permutation of 0..9, the same holds for Y, and the 100…

The task

Construct a pair of orthogonal Latin squares of order 10: two 10x10 arrays X and Y with entries in 0..9 such that every row and every column of X is a permutation of 0..9, the same holds for Y, and the 100 ordered pairs (X[i][j], Y[i][j]) are all distinct.
