Many different sources say that all the Somos-k sequences for k>7 have non-integer terms. However, none of them give a proof! Where can I find one? Thanks!

  • $\begingroup$ oeis.org/A030127 gives "Term at which n-Somos sequence first becomes nonintegral." Have you checked the references at that page? $\endgroup$ – Gerry Myerson Jun 21 '13 at 9:20
  • $\begingroup$ Yeah I looked at both of these pages and didn't find any proofs. It's possible that I'm just bad at looking though. $\endgroup$ – jalman Jun 21 '13 at 9:52
