The first column of this array is the sequence that rejects the sum of any previous pair of terms (the 2-Stöhr sequence A033627). The second column takes the remaining numbers and rejects the sums of pairs of its previous terms, etc.
The first column consists of all numbers equivalent to 1 mod 3, and also 2. The second column consists of all numbers equivalent to 3 mod 9 and 5 mod 9, and also 6. The k-th column includes 3^k, 2*3^k, and 4*3^k, and in general every term in the (k-1)-th column multiplied by 3.
