The "Error: Within" row shows the residual degrees of freedom, which is (n-1) where n is the number of replications per cell. In this case, the residual degrees of freedom is 16, which corresponds to (n-1) = 4 replications per cell. Therefore, the total number of observations is (4 replicates per cell) x (2 levels of factor A) x (2 levels of factor B) = 16.
