 A186514 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) before g(j) when f(i)=g(j), where f(i)=i^2 and g(j)=4+5j^2.  Complement of A186513. 4

 OFFSET 1,1 COMMENTS See A186219 for a discussion of adjusted joint rank sequences. The pairs (i,j) for which i^2=4+5j^2 are (L(2h),F(2h)), where L=A000032 (Lucas numbers) and F=A000045 (Fibonacci numbers). LINKS FORMULA a(n)=n+floor((1/10)(-4+sqrt(20n^2+6)))=A186513(n). b(n)=n+floor(sqrt(5n^2+4n+1/2))=A186514(n). EXAMPLE First, write 1..4..9..16..25..36..49..... (i^2) ......9.....24.......49.. (4+5j^2) Then replace each number by its rank, where ties are settled by ranking i^2 before 4+5j^2: a=(1,2,3,5,7,8,9,11,12,14,15,17,..)=A186513 b=(4,6,10,13,16,19,22,26,29,32,...)=A186514.
