%N Rectangular array T(n,k) by antidiagonals; rows are generalized Fibonacci sequences and every relatively prime pair (i,j) satisfying 1 <= i < j occurs exactly once.
%C In every row, the limiting ratio of consecutive terms is tau.
%F Recurrence for row n: T(n, k)=T(n, k-1)+T(n, k-2). Each row after the first begins with lexically least relatively prime pair not in previous rows.
