COMMENTS

The equivalent sequence for Zeta(3) repeated after very few terms. When, if ever, does this sequence start to repeat?


LINKS

Table of n, a(n) for n=1..41.


EXAMPLE

1/Pi = 0.31830988618379067153...
a(1)=0; a(2)=5 because the 5th decimal digit after the "0." is 0; a(3)=19 because the 19th digit is 5, etc.
