%N Solution of the complementary equation b(n)=a(a(n))+n; this is sequence b; sequence a is A136495.

%C b = 1 + (column 1 of Z) = 1 + A020942. The pair (a,b) also satisfy the following complementary equations: b(n)=a(a(a(n)))+1; a(b(n))=a(n)+b(n); b(a(n))=a(n)+b(n)-1; (and others).

%F Let Z = (3rd order Zeckendorf array) = A136189. Then a = ordered union of columns 1,3,4,6,7,9,10,12,13,... of Z, b = ordered union of columns 2,5,8,11,14,... of Z.

%e b(1) = a(a(1))+1 = a(1)+1 = 1+1 = 2;

%e b(2) = a(a(2))+2 = a(3)+2 = 4+2 = 6;

%e b(3) = a(a(3))+3 = a(4)+3 = 5+3 = 8;

%e b(4) = a(a(4))+4 = a(5)+4 = 7+4 = 11.
