COMMENT

Row sums give A014477: Sum(T(n,k): 0<=k<=n) = A014477(n-1);
central terms give A118415; T(2*k-1,k) = A058962(k-1);
T(n,1) = A000079(n-1);
T(n,2) = A007283(n-1) for n>1;
T(n,3) = A020714(n-1) for n>2;
T(n,4) = A005009(n-1) for n>3;
T(n,5) = A005010(n-1) for n>4;
T(n,n-1) = A118417(n-1) for n>1;
T(n,n) = A014480(n-1) = A118413(n,n);
A001511(T(n,k)) = A002024(n,k);
A003602(T(n,k)) = A002260(n,k).
