A186542 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) after g(j) when f(i)=g(j), where f(i)=i^2 and g(j)=-2+3j^2. Complement of A186541. 4

%N Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) after g(j) when f(i)=g(j), where f(i)=i^2 and g(j)=-2+3j^2. Complement of A186541.

%C See A186219 for a discussion of adjusted joint rank sequences.

%H Sean A. Irvine, <a href="/A186542/b186542.txt">Table of n, a(n) for n = 1..10000</a>

%F a(n)=n+floor(sqrt((1/3)n^2+5/6))=A186541(n).

%F b(n)=n+floor(sqrt(3n^2-5/2))=A186542(n).

%e First, write

%e 1..4..9..16..25..36..49..... (i^2)

%e .........10.....25.....46.. (-2+3j^2)

%e Then replace each number by its rank, where ties are settled by ranking i^2 after -2+3j^2:

%e a=(2,3,4,6,8,9,11,12,14,15,17,18,..)=A186541

%e b=(1,5,7,10,13,16,19,21,24,27,29...)=A186542.

%t (See A186541.)
