Hi Aaro
If you call simplify, it simplifies a little bit.
I guess it's not necessarily a good idea to auto-expand things like
binomial(n, 5). Go ahead and open another issue for that if you want.
Probably it should be changed to remain unevaluated, and to expand
with expand(func=True).

... but the problem is that it expands the binomial function too and
the output is not so readable as a result:
t**5*(-n*(n - 4)*(n - 3)*(n - 2
Thanks for replying.

Hello. Trying to execute the following minimal example throws SymPy
into an infinite loop. (Obviously this is an extract from my actual
program.) I tried debugging using eric5 but beyond that the problem
occurs within the Ra() function, I couldn't find out anything. Can
please anyone tell me what I
