Extracting Embedded OOA
Given a (digital) (m−k, m, s)-net N in base b, a (linear) ordered orthogonal array A with parameters OOA(bm, s, Sb, T , k) can be constructed for all T with T ≥ k/s [1] [2]. If N is digital over Fb, A is linear and its dual is a linear [(s, T ), sT −m, k + 1]-NRT-code over Fb.
Construction
A is formed based on the T leading digits in the b-adic expansion of the coordinates of the points of N. More formally, A is obtained from N as
with ηi,j : Sb↔{0,…, b – 1} denoting arbitrary bijections.

For T ≥ k this process can be reversed by net defined by OOA
