%N Secondary Wythoff Array read by antidiagonals.
%C (1) Delete the odd numbered rows and get twice the Wythoff array, A035513. (2) Subtract 1 from the even numbered rows and get the odd numbered rows. (3) As a sequence, this is a permutation of the positive integers. (4) The array is a dispersion and an interspersion. (5) Let c = ordered union of odd numbered columns and let d = ordered union of even numbered columns; then c and d are the unique solutions of the complementary equation d(n)=c(c(n))+2 and also of the complementary equation d(n)=c(n)+2*Floor[(n+2)/2]. (6) c=A137708, d=A137709.
%F Odd numbered rows: r(n)=r(n-1)+r(n-2)+1, Even numbered rows: r(n)=r(n-1)+r(n-2).
