A186388 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) before g(j) when f(i)=g(j), where f(i)=6i and g(j)=j(j+1)/2 (triangular number). Complement of A186387.

%N A186388 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) before g(j) when f(i)=g(j), where f(i)=6i and g(j)=j(j+1)/2 (triangular number).  Complement of A186387.
%e A186388 First, write
%e A186388 ......6.....12..18....24..30. (6i)
%e A186388 1..3..6..10...15....21..28... (triangular)
%e A186388 Then replace each number by its rank, where ties are settled by ranking 6i before the triangular:
%e A186388 a=(3,6,8,10,12,13,15,17,...)=A186387
%e A186388 b=(1,2,4,5,7,9,11,14,16,...)=A186388.
