A186390 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) after g(j) when f(i)=g(j), where f(i)=6i and g(j)=j(j+1)/2 (triangular number). Complement of A186389.

%e A186390 First, write
%e A186390 ......6.....12..18....24..30. (6i)
%e A186390 1..3..6..10...15...21...28... (triangular)
%e A186390 Then replace each number by its rank, where ties are settled by ranking 6i after the triangular:
%e A186390 a=(4,6,8,10,12,14,15,17,...)=A186389
%e A186390 b=(1,2,3,5,7,9,11,13,16,...)=A186390.
