A186323 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 heptagonal numbers. Complement of A186322. 4

EXAMPLE
First, write
1..4...9..16....25...36...49...64.. (squares)
1....7.......18....34........55.... (heptagonal)
Replace each number by its rank, where ties are settled by ranking the square number after the heptagonal:
a=(2,3,5,6,8,10,11,13,...)=A186322
b=(1,4,7,9,12,15,17,20,...)=A186323.
