Trivial Upper Bound on the Number of Factors

Requiring s ≤ ∞ is a trivial upper bound on the number of factors s of an orthogonal array OA(M, s, Sb, k) because it allows arbitrarily large values of s.

Orthogonal Arrays Meeting this Bound

Orthogonal arrays with arbitrarily large s exist. In particular, OAs with k = 0 (arbitrary OA) and k = 1 (line OA / dual of parity check code) can have arbitrarily large s for any fixed M.
