Jon E. Schoenfield, Table of n, a(n) for n=1..1000, using data from A001620.

Example

A001620(12)=1 and A001620(13)=5, so a(7)=1+5=6.
A001620(14)=3 and A001620(15)=2, so a(8)=3+2=5.
A001620(16)=8 and A001620(17)=6, so a(9)=8+6=14.
A001620(18)=0 and A001620(19)=6, so a(10)=0+6=6.
A001620(20)=0 and A001620(21)=6, so a(11)=0+6=6, etc.
