Recurrence sequence based on positions of digits in decimal places of e.

Links

Table of n, a(n) for n=0..18.

Example

So for example, a(2)=13 because 13th digit of e after decimal point is 0.
a(3)=27 because 27th decimal digit of e is 13, a(4)=62 because 62nd to 63rd decimal digits of e form "13" and so on.
