Comment (by vdelecroix):
Hi Nathann,
I do not agree with your corrections. By definition, the holes are subsets
of the ground set `V = {0,...,n-1}`. Perhaps it depend on where we read
the definition.
Could we just get rid of the caching and return list of lists in the very
same way as `orthogonal_array`? The time needed to find 3 disjoint blocks
is not big compared to the time you need to build an orthogonal array. It
would make more sense to implement the caching at the level of
`orthogonal_array`. And I think, it would better if done in another
ticket.
