The following few lines lead to a crash in Sage 10.0, with error message
"TypeError: Not an element of the order." Is this an error on my part?
K. = NumberField(3*x^2 + 1)
P. = ProjectiveSpace(K, 1)
phi = DynamicalSystem_projective([a*(z^2 + w^2),z*w])
phi.canonical_height(P(a,1))

How can one create a subgroup of the ideal class group of a number
field by specifying a list of ideals to use as generators? I've tried
using the subgroup commands, with no success. Any help would be much
appreciated.

The dictionary is exactly what I needed. Thanks!

Is there a data structure in Python that would allow me to do the
following:
I have a list of positive integer pairs, say [[1,2], [1,3], [2,5]].
For each pair [i,j] in my list I need to store in memory a number
c[i,j] which is a floating point number with some large precision. I'd
like to create s
Great! So it looks like maybe it'll be working soon.

Unfortunately, I can't do these sorts of tests because I can't rebuild
the sage library on my machine right now. However, the only change I
made to the height function was a couple of parentheses, so the
functionality should not be affected in any way, only the output.

After many difficulties and confusions, I think I understood enough
about Mercurial queues to upload a patch. Thanks for your help!

OK, yes, I'm running Lion with Xcode 4.

I just made a new installation of Sage 4.7.1 and I tried to build the
library (although I haven't made any changes to it). I get this error

Thanks, Maarten. I'm getting stuck when I run hg_sage.commit() . I do
not get a text editor to open as described in the links you gave me.
Instead, I get the same info as when I ran hg_sage.diff(), just a list
of the changes I made. Any idea of why this might happen?

There is a problem with the global_height function for elements of
number fields. The fix would be very simple, just need to add two
parentheses to the code. Below is an example of the problem. I'm
running Sage version 4.7 on Mac OS X version 10.6.8.
sage: K. = QuadraticField(2)
sage: s.global_hei
