answered Is g( ) rational if it looks that way on a large rational subset?

comment Is g( ) rational if it looks that way on a large rational subset?
@DavidHolmes The question makes sense. Maybe it's clearer to ask whether, given the conditions, there is a rational function $g_1$ satisfying the same hypotheses as $g$.

comment Parity-check matrix for code with variable block size and minimum distance
The main conjecture of MDS codes states that there is no code with length + 1 = dimension + min. distance (writing out since your notation is nonstandard) for length > q+2. You want to relax this to length=dim. + distance but want length up to $q^2$. I doubt it can be done.

comment Find all possible rational values of the parameter of a parametric cubic such that it is reducible
@j.c. But then wouldn't changing $\eta$ to $-\eta$ switch between the two?

But what does it actually mean? I would understand $\beta_+ = 1 + \eta, \beta_- = 1 - \eta$ but I don't actually know the difference between $1 \pm \eta$ and $1 \mp \eta$.

@j.c. Oh, I missed that, there are two different betas in the polynomial. I need to redo this. Thanks.

@LorenzMenke I said the curve is rational, as in parametrizable by rational functions.

comment Mazur secret Bourbaki report “Analyse p-adique”
@DanielMoskovich Barry Mazur is not dead, far from it, in fact he even has a webpage where posts preprints sometimes. I'd suggest that Keith email Barry the scanned pdf so he can put it on his webpage or on the arxiv if he wants.

comment What is a Frobenioid?
"Perhaps this is a key reason he can't understand why the rest of us are so reluctant." So you empathize with him even though he doesn't empathize with you.
