Pochhammer[a, n] gives the Pochhammer symbol (a)n.
Evaluate numerically: In[1]:=Pochhammer[10, 6] Out[1]=3603600 Evaluate symbolically with respect to n: In[1]:=Pochhammer[n, 5] Out[1]=n (1 + n) (2 + n) (3 + n) (4 + n) In[2]:=Pochhammer[n, -5] Out[2]=1/((-5 + n) (-4 + n) (-3 + n) (-2 + n) (-1 + n)) Plot over a subset of the reals: In[1]:=Plot[Pochhammer[x, 1/2], {x, -.5, 4}] Out[1]=
