vastly improved the proof.

Could you please give an insight into that? Or am I not thinking deeply enough about the anwsers already given to me?? | |
| Feb 21, 2011 at 5:57 | comment | added | Theo Johnson-Freyd | One thing that's disappointing in my proof is the coincidence. Another is that it doesn't highlight the symmetry under $r \leftrightarrow -s$. There should be a similar formula with $s \leadsto -s$, and a good exercise is to give a similar proof of that formula. | |
