        Vectors are entered in the following way: 
                "{a1, ... ,an}", n>0.

        The following functions are available for vectors:

        +           denom       mtoi        scalar  
        -           elsubst     nftopol     vcoef
        *           gftopol     num         zvconstr 
        ==          mod         puto
        !=


        '+'             means   addition;

        '-'                     subtraction;

        '*'                     multiplication;

        '=='                    equal;

        '!='                    not equal;

        'denom'                 denominator;

        'elsubst'               element substitution in matrices or vectors;

        'gftopol'               Galois-field to polynomial;

        'mod'                   module homomorphism;

        'mtoi'                  modular to integer;

        'nftopol'               number field to polynomial;

        'num'                   numerator;

        'puto'                  display internal representation;

        'scalar'                euclidian scalar product;

        'vcoef'                 vector coefficient;

        'zvconstr'              zero vector construction.
