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 First, write
`

`%e ......6.....12..18....24..30. (6i)
`

`%e 1..3..6..10...15....21..28... (triangular)
`

`%e Then replace each number by its rank, where ties are settled by ranking 6i before the triangular:
`

`%e a=(3,6,8,10,12,13,15,17,...)=A186387
`

`%e b=(1,2,4,5,7,9,11,14,16,...)=A186388.
