A186498 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) before g(j) when f(i)=g(j), where f(i)=3i-2 and g(j)=j-th triangular number. Complement of A186497. 2

%N Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) before g(j) when f(i)=g(j), where f(i)=3i-2 and g(j)=j-th triangular number. Complement of A186497.

%e First, write

%e 1..4..7.10..13..16..19..22..25..28..31. (3i-2),

%e 1.3..6..10....15.......21.......28.....(j(j+1)/2).

%e Then replace each number by its rank, where ties are settled by ranking 3i-2 before j(j+1)/2:

%e a=(1,4,6,7,9,11,12,14,15,16,18,...)=A186497,

%e b=(2,3,5,8,10,13,17,20,24,29,33,..)=A186498.

%t (See A186497.)

%Y Cf. A186350, A186497, A186499, A186500.
