FORMULA

a(n)=n+floor(sqrt((1/3)n^2+5/6))=A186541(n).
b(n)=n+floor(sqrt(3n^25/2))=A186542(n).


EXAMPLE

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