EXAMPLE

First, write the triangular and octagonal numbers:
1..3..6.....10..15..21..28
1........8..........21......
Then replace each by its rank, where ties are settled by ranking the triangular number after the octagonal:
a=(2,3,4,6,7,9,10,11,13,...)=A186275.
b=(1,5,8,12,15,19,22,26,...)=A186276.
