That was the link I intended to post - instead I posted the same link twice.
As you can see, 8080 would be a more sensible default port, avoiding
8000 which is for remote desktop management.

Now this would be more useful:

sage: L. = NumberField(x^2+x+1)
sage: K.has_coerce_map_from(L)
False
sage: L.has_coerce_map_from(K)

Hi!
When defining a number field, it is optional to provide a canonical
embedding into the real lazy field.
If two number fields are defined by the same polynomial and the same
generator name, they are still considered different, if only one of
them defines a canonical embedding.
Example:
sage:
I have thought for some time that it would be an improvement to have
groups. work in much the same manner as graphs. and to
have some of the less generally-useful groups moved out of the global
namespace (after a proper deprecation of that behavior).
And Dima's point (as on #9136) about buildin
Hi Dave,
to be able to process a *.pyx file (as the doctest definitely seems to
do), yes, you need a compiler (either C or even C++, depending on
the .pyx file). If you want to load/attach *.pyx files, the same
applies. (Behind the scenes, Cython is used to generate out of the
*.pyx file a *.c, or

Are you reinventing the wheel? :-)
One should be able to import into Sage any graph that GAP can make
using its package Grape. Grape is essentially doing what you seem to
be doing: takes a permutation group and constructs a graph invariant
under it.
E.g.
gap> LoadPackage("grape");
gap> G:=NullGrap

The default port fo the Sage server is port 8000 and not port 8080. Is
there any good reason for this?
http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
lists port 8080 as an anternate HTTP server, bt notes of 8000 that
"8000 is sometimes erroneously used instead of port 8080"

This sounds reasonable to me. I know that in general we do not want
to try to coerce from Z/nZ to GF(n) for prime n since we do not want
to prove primality except deliberately. The reverse coercion is a
