 OFFSET 1,2 COMMENTS The equivalent sequence for Zeta(3) repeated after very few terms. When, if ever, does this sequence start to repeat? LINKS 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. CROSSREFS Cf. A098266 (for e version), A097614 (for Pi version), A098289 (for log(2) version), A098290 (for Zeta(3) version), A049541 for digits of 1/Pi.
