Comment #2 on issue 1598 by ondrej.certik: New polynomials manipulation
module
http://code.google.com/p/sympy/issues/detail?id=1598
Wow, Mateusz, you are a genius.
I tried this:
In [1]: a = (x+y+z)**20
In [2]: b = a.expand()
In [6]: time factor(b)
CPU times: user 3.08 s, sys: 0.00 s, total: 3.08 s
Wall time: 3.11 s
Out[7]:
20
(x + y + z)
And try maxima, it can't do it! :) So we are slowly overtaking maxima,
that's exciting.
This fails for me, but it's minor:
