Added crossref from G.order() to G.degree() in permgroup
Fix alarm doctest (but not the underlying problem)
Reviewer's Commit: Fixed the failing doctest.
Trac #16667: Random failure in polynomial_element.pyx

This doctest was introduced in #16162. It fails quite reliably (maybe
80% of the runs) on the AIMS snapperkob (Ubuntu 14.04 x86_64) buildbot:
{{{
sage: K.<a> = GF(2**8) ## line 1416 ##
sage: x = polygen(K) ## line 1417 ##
sage: alarm(1) ## line 1418 ##
sage: (x**1000000+x+a).any_root() ## line 1419 ##

**********************************************************************
----------------------------------------------------------------------
sage -t --long src/sage/rings/polynomial/polynomial_element.pyx  # Timed
out (and interrupt failed)
}}}

See #16850 for the underlying issue, this ticket is just to fix the
doctest failure.

Trac #16842: Add crossreference to degree in order for a permutation group

{{{
sage: G = SymmetricGroup(4)
sage: G.order?
Type:            instancemethod
String form:     <bound method SymmetricGroup_with_category.order of
Symmetric group of order 4! as a permutation group>
File:
/Applications/Sage-6.0.app/Contents/Resources/sage/local/lib/python2.7
/site-packages/sage/groups/perm_gps/permgroup.py
Definition:      G.order(self)
Docstring:
   Return the number of elements of this group.
}}}

Would like to add a line:

See also: G.degree()
