A differential -form is a Tensor of Rank which is antisymmetric under exchange of any
pair of indices. The number of algebraically independent components in -D is , where this is a
Binomial Coefficient. In particular, a 1-form (often simply called a ``differential'') is a quantity

Similarly, a 4-form can be constructed from Wedge Products of two 2-forms or four 1-forms
