Is there a particular reason why the log_repr in finite fields returns a
string instead of an integer?
Actually, more important than that, the following fails:
F=GF(5)
r=F.multiplicative_generator()
r.log_repr() <--- comes back with an error
log(r,r) < also comes back with an error.
This is n

I am not so sure this is the proper fix, but you ought to open a
ticket for the issue anyway.
Thanks,

Hi Chris and others,
Certainly there are betters ways to do that.
For this and similar problems in propositional logic,
I would suggest to wrap a SAT solver.

Hi All,
I'm currently trying to implement a function for the propositional
calculus package that would determine if two statements are logically
equivalent. The usage would be something along the lines of:
sage: a = propcalc.formula('a | (b&c)')
sage: b = propcalc.formula('(x&y) | z')
sage: a.e
Hello folks,
since Sage on Solaris is more than a little tricky to build at the
moment I packaged up a 3.0.5 build at

I think the solution is just to define __rmul__ :
sage: x = PolynomialRing(QQ,'x').gen()
sage: f = Piecewise([[(0,1),1*x^0]])
sage: r = f*2
sage: r = 2*f

Sage has some rules that tell it to convert
Dear Mike,
I have mul and rmul in my class definition. This all works fine in
python, but it fails when using sage integers/floats.
If I call
sage: a = MyFloat(2)
sage: 3*a
by adding some extra code, I see that MyFloat.__mul__(self,other) is
called, and in fact the type of both self and other is
I fully agree with David.
I started using Mathematica during my PhD project, when the equations
I was dealing with just became too complex to be dealt with using
paper and pencil. I must say that I would not have been able to finish
my PhD without such a software. I was very glad to find out that
