| Feb 18, 2013 at 15:34 | comment | added | Sándor Kovács | I totally agree [with Graham]. It was lucky that I could recognize the geometry behind this particular example, but Macaualy 2 is useful when that's hard to do. | |

| Feb 18, 2013 at 13:49 | comment | added | Graham Leuschke | I also wish Sándor [and all people 'like' and 'unlike' him] nothing but long life and happiness, but I do want to say that while my first answer is admittedly pretty black-boxy, the second one and Youngsu's comment following are both easy and instructive to do by hand, and that it's only by doing many such examples that we can get the kind of algebraic intuition that serves us [i.e. me] when we [i.e. I] meet examples that are not so susceptible to geometry. | |
| Feb 18, 2013 at 12:50 | comment | added | Georges Elencwajg | Dear @wccanard, you write "Then where would we be [When Sándor dies]?" Answer: in a much worse world. I study mathematics in order to understand what is going on. Pushing buttons and having an answer spit at me teaches me nothing. Long life to Sándor! | |

| Feb 18, 2013 at 7:28 | comment | added | user30035 | Given that these computations seem to be relatively easy to do on a computer these days (see Graham Leuschke's answer) I think my main fear is that people like Sandor Kovacs might one day die out :-/ Then where would we be? | |
