 Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 60, we have over 367,000 sequences, and we’ve crossed 11,000 citations (which often say “discovered thanks to the OEIS”). Other ways to Give

 OFFSET 1,2 COMMENTS Could be made less gigantic by omitting final terms in continued fraction, which are always 2*c0. LINKS Table of n, a(n) for n=1..19. FORMULA a(n) = A059884(A059903(n)). EXAMPLE sqrt(3)=1+[1,2] so a(3) is encoded as: .....0 0 0 0 1 -> 1 ....... 1 . 0 .-> 2 -------------- .....000100001 = 33. CROSSREFS A059903, A059884, A003285.
