Table of n, a(n) for n=1..82.

Example

First, write
1..4...9..16....25..36....49..64...  (squares)
1....8.......21........40........65. (octagonal)
Replace each number by its rank, where ties are settled by ranking the square number after the octagonal:
a=(2,3,5,6,8,9,11,12,14,...)=A186326
b=(1,4,7,10,13,15,18,21,...)=A186327.
