Table of n, a(n) for n=1..39.

Example

a(4)=50 because the sum of last four *digits* of the sequence beginning with 0,0,0,8, (three zeros followed by a 8) enters in a loop whose length is 50 terms; so a(4)=50
a(5)=171 because "Sum of last five digits" beginning with 0,0,0,0,8 enters in a cycle of 171 terms.
