Good point. However, I copied the version number from the README file,
which says 10.4, because copying from the DMG is messier. The DMG
claims to be 10.6.
I also have installed XCode 3.2, with GCC 4.2.1 build 5646, which may
help. For obscure reasons the XCode installation complained about a
coup
Yes, as David points out, you definitely want the 10.6 binary:
sage-4.5.3-OSX-64bit-10.6-i386-Darwin.dmg

Really sorry, I didn't give details. It was a 64 bit Mac running sage
version 4.5.2. But now I am running 4.5.3 and it seems to be working
fine.

EXACTLY what binary are you running, and on exactly which computer?
Do you have this problem if you

Quite apart from any problems there may be with the sympow
implementation, there is another bug here: for curves in the
database, the modular degree is known from the database, as you can
see here:
sage: E = EllipticCurve('11a1')
sage: E._EllipticCurve_rational_field__modular_degree
1
But for so
But 10.4 is not snow leopard. I think 10.4 is tiger.
Did you also try downloading and installing the 10.6 version?

I just downloaded Sage 4.5.3-OSX10.4-intel-i386-Darwin and set out to
install it on:
Hardware: MacBook Pro 5.1, Core2 Duo, 2.4 GHz, 4 GB.
Software: OS X 10.6.4 64-bit
Following instructions in the file sage-README-osx.txt , items 1), 2),

Hi Alasdair!
What about this:
sage: F.=GF(2^8,name='x')
sage: R.=PolynomialRing(GF(2))
sage: p = F.random_element()
sage: p
x^7 + x^5 + x^4 + x
sage: pp = p.polynomial()
sage: pp(x=y)
y^7 + y^5 + y^4 + y
The only difference to your approach is that R is defined over the
field GF(2) rather than t
Hi Alasdair,
F.=GF(2^8,name='x')
R.=PolynomialRing(Zmod(2))
p = F.random_element()
p.subs(x=y)
Basically, I have an object which is created as an element of a finite
field, which I then need to treat as an element of a ring. If I try:
pp = p.polynomial()
pp.subs(x=y)
And what do you think
The following shows what I'd like to do:
F.=GF(2^8,name='x')
R.=PolynomialRing(Zmod(2))
p = F.random_element()
p.subs(x=y)

pp.subs(x=y)
You could also make a sage matrix from a:
A = matrix(a)
and then perhaps its methods would do what you want. For example, you
could do
A.change_ring(QQ)
to convert to rational numbers.

Could you post more information of the problem?
