a(1)=0; for i>=1, a(i+1)=position of first occurrence of a(i) in decimal expansion of 1/e.

COMMENTS

Recurrence sequence based on positions of digits in decimal places of 1/e.

LINKS

Table of n, a(n) for n=0..19.

EXAMPLE

So for example, a(2)=27 because 27th digit of 1/e after decimal point is 0.

a(3)=88 because 88th decimal digit of 1/e is where 27 appears,

a(4)=308 because 308th to 309th decimal digits of 1/e form "88" and so on.
