%N A186494 Adjusted joint rank sequence of (f(i)) and (g(j)) with f(i) before g(j) when f(i)=g(j), where f(i)=5i and g(j)=j-th pentagonal number.  Complement of A186493.
%e A186494 First, write
%e A186494 ....5..10..15..20..25..30..35..40.. (5i),
%e A186494 1..5......12......22............35..(pentagonal numbers).
%e A186494 Then replace each number by its rank, where ties are settled by ranking 5i before the pentagonal number:
%e A186494 a=(2,4,6,7,9,10,11,13,14,15,17,...)=A186493,
%e A186494 b=(1,3,5,8,12,16,21,26,32,39,46,..)=A186494.
