Table of n, a(n) for n=1..16.

Example

a(4)=12 because the sum of last four *digits* of the sequence beginning with 0,0,0,3, (three zeros followed by a 3) enters in a loop whose length is 12 terms; so a(4)=12
a(5)=171 because "Sum of last five digits" beginning with 0,0,0,0,3 enters in a cycle of 171 terms.
