        "matrix over Z/2Z in special bit notation"
        SYNTAX: M = mam2(n,l_1,...,l_m)

        n is an expression whose value is a positive single precision 
        number. l_1,...,l_m are integers with 0 <= l_i <= 2^n-1. 
        The l_i represent lines of a mxn-matrix over Z/2Z in
        special bit notation. 
        For example: The matrix { { 1 1 1 }
                                  { 1 0 1 }
                                  { 0 1 1 }
                                  { 0 0 1 } }
        is represented by (3,7,5,3,1).
        
        M is assigned the matrix over Z/2Z, represented by
        (n,l_1,...,l_m).

        
        Example 1: (correct)

                mam2(7,2,5,1,7)


        Example 2: (incorrect)

                mam2(2,5,6)
