Discarding Parts of the Base for OAs

Given an orthogonal array A with parameters OA(M, s,Fpu, k), an OA(M, s,Fp, k) Aʹ with 1 ≤ uʹ ≤ u can be constructed. If M is not a power of p, the resulting OOA listed by MinT is Aʹ duplicated pv times with v such that the number of runs is equal to the smallest power of p exceeding M.

Construction

Let φ : FpuFp denote an arbitrary surjective linear mapping. The resulting OA Aʹ is obtained from A as

Aʹ = {(φ(xi))i=1,…, s  :  xA}.
