COMMENT

The respective period lengths are given by A001175(n-1) (which is the Pisano period to n-1) for n>=2.

EXAMPLE
|
a(3)=8 since the digital sum analogue base 3 of the Fibonacci sequence is 0,1,1,2,3,3,2,3,3,... where the pattern {2,3,3} is the periodic part (see A131294) and sums up to 2+3+3=8. a(4)=30 because the pattern base 4 is {2,3,5,5,4,3,4,4} (see A131295) which sums to 30.
