Comment (by vdelecroix):
Hi Nathan,
Few remarks that would me help me for the review
* In the function transversal_desing
* the arguments are ordered k,n but in the definition n,k is used.
* could you give the definition with t
* In the function orthogonal_arrays
* you should defined what is a (k,n,t) orthogonal array.
* the documentation says that only t=2 is available but it does not
prevent you to define it in that generality.
* I guess that if k >= n+t there is no (k,n,t) orthogonal array. Do
you know that ? If this is true, please more explicit in the error
rather than `NotImplementedError`: I don't know how to build this
orthogonal array!" I would prefer "`EmptySetError`: there exist no
(k,n,t) orthogonal array with k >= n+t"
