Oct 30, 2010 at 18:12 | comment | added | JBL | Ah, I see, it's just that $n \leq 2$ and $n \leq 4$ are meant to be $n \geq 2$ and $n \geq 4$. | |
Oct 30, 2010 at 15:30 | comment | added | JBL | (Part of the reason it's not clear is that for either interpretation, at least one of the bounds you've written down is wrong.) | |

Oct 30, 2010 at 15:20 | comment | added | JBL | It's not clear what sort of lattice you're looking for. Lattices (posets) on unlabeled nodes are at oeis.org/A006966 -- on labeled nodes are oeis.org/A055512 $$ $$ I found this by putting the word "lattice" and the first few terms (computed by hand) into the OEIS: oeis.org/Seis.html | |
