Table of n, a(n) for n=1..81.

EXAMPLE

First, write

...5..10..15..20..25..30..35..40... (5i),

1..5......12......22............35..(pentagonal numbers).

Then replace each number by its rank, where ties are settled by ranking 5i after the pentagonal number:

a=(3,4,6,7,9,10,12,13,14,15,17,...)=A186495,

b=(1,2,5,8,11,16,20,26,32,38,46,..)=A186496.
