I think that I have enough room for an install.
The first install failed for lack of space and then I wrote to the
host a
These are curiosity questions. Hope someone knows, but perhaps some
are just buried a little deeper in the documentation than I thought.
1. The solve wrapper of maxima does some nice stuff symbolically, but
of course it can't handle everything, like
sage: solve(x^5-x-12,x)
[0 == x^5 - x - 12]

FYI, this is now fixed. I couldn't get to it until now, since I was
"off the grid".

Tthe '?' and '??' operators only handle defined method
Just for reference, two comments on the documentation for quaternions:
If x is an element of L as below, then neither x? nor x?? returns any
information about methods that apply to x.
Second, in the documentation on quaternions in the reference manual,
there is no reference that
I could find to
Although Justin's solution certainly works, one might consider adding
a "real_part()" function to the quaternion class. But it would not do
to call the function "real_part" since of course it depends on the
ground field (which in the example is QQ and not RR).
I am CC'ing sage-devel since this m

I want to extract the "real part" of a quaternion, i.e., if
L. = QuaternionAlgebra(QQ,-1,-1);
and a is in L, then I want the coefficient of 1 in the expansion of as
a linear
combination of 1, i, j and k.
Is there a way to do this? A graceful way?

Thanks for the quick reply. I tried the command
sage: install_package("gap_packages-4.4.10_4")
After listing many files that it was installing, I got the following
error message:

Just one comment: a simple-minded user might say that evaluating
sum(b) where b has at least one entry need not actually require any
coercion of 0, since it only needs to do b[0]+b[1]+... . I know that
is not how sum() is defined, but it could be -- expect that sum() is
pure python.
