A186357 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) after g(j) when f(i)=g(j), where f(i)=3i and g(j)=j(j+1)/2 (triangular number).  Complement of A186357. 2

Table of n, a(n) for n=1..90.

EXAMPLE

First, write

...3..6..9....12..15..18..21..24.. (3*i)

1..3..6....10.....15......21.... (triangular)

Then replace each number by its rank, where ties are settled by ranking 3i after the triangular:

a=(3,5,6,8,10,11,13,14,15,..)=A186356

b=(1,2,4,7,9,12,16,19,23,...)=A186357.
