Create an orthogonal array using the Addelman-Kempthorne algorithm with 2q^3 rows.
Source: R/createOA.R
createAddelKemp3.RdThe addelkemp3 program produces
OA( 2*q^3, k, q, 2 ), k <= 2q^2+2q+1, for prime powers q.
q may be an odd prime power, or q may be 2 or 4.
Details
From Owen: An orthogonal array A is a matrix of n rows, k
columns with every element being one of q symbols
0,...,q-1. The array has strength t if, in every n by t
submatrix, the q^t possible distinct rows, all appear
the same number of times. This number is the index
of the array, commonly denoted lambda. Clearly,
lambda*q^t=n. The notation for such an array is OA( n, k, q, t ).
