Cylinder Cutting

The maximum number of pieces into which a cylinder can be divided by $n$ oblique cuts is given by

f(n)={n+1\choose 3}+n+1={\textstyle{1\over 6}}(n+2)(n+3),

where ${a\choose b}$ is a Binomial Coefficient. This problem is sometimes also called Cake Cutting or Pie Cutting. For $n=1$, 2, ... cuts, the maximum number of pieces is 2, 4, 8, 15, 26, 42, ... (Sloane's A000125).
