%F A186542 a(n)=n+floor(sqrt((1/3)n^2+5/6))=A186541(n).
%F A186542 b(n)=n+floor(sqrt(3n^2-5/2))=A186542(n).
%e A186542 First, write
%e A186542 1..4..9..16..25..36..49..... (i^2)
%e A186542 .........10.....25.....46.. (-2+3j^2)
%e A186542 Then replace each number by its rank, where ties are settled by ranking i^2 after -2+3j^2:
%e A186542 a=(2,3,4,6,8,9,11,12,14,15,17,18,..)=A186541
%e A186542 b=(1,5,7,10,13,16,19,21,24,27,29...)=A186542.
