I don't want to code for-loops each time,
but how can I factor a pochhammer symbol for a given degree?
The documentation simply says
---------------------------------------------------------------
pochhammer(x,3);
---------------------------------------------------------------
for me that does not work as the following maxima run shows
---------------------------------------------------------------
$ maxima -b pochhammer.max

(%i3) pochhammer(x,3)
(%o3) pochhammer(x,3)
(%i4) makegamma(pochhammer(x,3))
(%o4) gamma(x+3)/gamma(x)
(%i5) expand(pochhammer(x,3))
(%o5) pochhammer(x,3)
(%i6) ratsimp(pochhammer(x,3))

(%i7) factor(pochhammer(x,3))
(%o7) pochhammer(x,3)
