That's a useful generalization I hadn't thought of. For sake of my current notation though, the assumption is necessary. Thanks. Dec17 comment Root of prime numbers Ah! Yes, for that approach you do need lowest terms. I prefer this one because the contradiction is more immediate. Dec17 comment Root of prime numbers @CameronBuie Thanks. I'm just used to using natural numbers in the number theory sense. Also, I think since the contradiction lies in the fact that the left hand side has an odd number of terms in prime factorization, it doesn't matter if the fraction is reduced or not. Dec17 comment Root of prime numbers I approved the edit, but since I specified natural numbers (which don't include $0$) I'm not entirely sure it was necessary. Dec17 awarded Custodian Dec17 reviewed Approve Root of prime numbers Dec17 answered Root of prime numbers Dec16 answered Meaning of a regular polytope Dec14 comment Category theory text that defines composition backwards? I started reading the composition operator as "after" and it has really helped. You would read $g\circ f$ as $g$ after $f$ and then you always know which one comes first. Dec10 accepted Find the equations for the hyperplanes of symmetries of the $n$-cube Dec10 comment Find the equations for the hyperplanes of symmetries of the $n$-cube Perfect. I didn't realize there was a name for cubes and cross-polytopes together, but that makes sense because they're dual. Thanks. Dec10 comment Find the equations for the hyperplanes of symmetries of the $n$-cube I'm looking for the three that generate every other hyperplane.
