%N A186496 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) after g(j) when f(i)=g(j), where f(i)=5i and g(j)=j-th pentagonal number.  Complement of A186495.
%e A186496 First, write
%e A186496 ...5..10..15..20..25..30..35..40... (5i),
%e A186496 1..5......12......22............35..(pentagonal numbers).
%e A186496 Then replace each number by its rank, where ties are settled by ranking 5i after the pentagonal number:
%e A186496 a=(3,4,6,7,9,10,12,13,14,15,17,...)=A186495,
%e A186496 b=(1,2,5,8,11,16,20,26,32,38,46,..)=A186496.
