COMMENTS

a(20) > 5*10^7.

LINKS

Table of n, a(n) for n=1..19.

FORMULA

a(1)=0, p(i)=position of first occurrence of a(i) in decimal places of sqrt(e), a(i+1)=p(i).

EXAMPLE

sqrt(e)=1.6487212707001281468...

So for example, with a(1)=0, a(2)=9 because 9th decimal place is 0; a(3)=60 because 9 appears at decimal place number 60 and so on.
