%N Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) after g(j) when f(i)=g(j), where f and g are the squares and octagonal numbers. Complement of A186326.

%e First, write

%e 1..4...9..16....25..36....49..64... (squares)

%e 1....8.......21........40........65. (octagonal)

%e Replace each number by its rank, where ties are settled by ranking the square number after the octagonal:

%e a=(2,3,5,6,8,9,11,12,14,...)=A186326

%e b=(1,4,7,10,13,15,18,21,...)=A186327.

%t (See A186326.)

%Y Cf. A186324, A186325, A186326.

%K nonn
