| Jul 11, 2013 at 0:34 | comment | added | ARupinski | Is there some reason you didnt factor the denominator for the $n=4$ case into its squareful and squarefree parts like the others? Note that its squarefree part also contains 7 (along with 3 and 5)... | |
| Jul 10, 2013 at 19:21 | comment | added | Igor Rivin | Very cool! Still doesn't explain the humongous prime factors, though :( | |
| Jul 10, 2013 at 19:13 | comment | added | Steve Huntsman | Indeed there is. See (3.9) of arxiv.org/abs/math/9902004 | |
| Jul 10, 2013 at 19:09 | comment | added | Igor Rivin | Cool! There may be a theorem lurking here... | |
| Jul 10, 2013 at 18:58 | comment | added | Steve Huntsman | These seem to be related to the numerators and denominators of permanents of the Hilbert matrices: oeis.org/A101812 oeis.org/A101811 oeis.org/A092326 | |
