Abstract
We give the general form of the vertex corresponding to the interactio n of an arbitrary number of strings. The technique employed relies on the ''comma'' representation of string field theory where string field s and interactions are represented as matrices and operations between them such as multiplication and trace. The general formulation present ed here shows that the interaction vertex of N strings, for any arbitr ary N, is given as a function of particular combinations of matrices c orresponding to the change of representation between the full string a nd the half string degrees of freedom.
