(X,,.... X, IXi Z (b)= Xi (i= 1,..., II)), where z is a homomorphism of the braid group B, to the group of automorphisms of the free group (x1,.., x,) called the Artin representation (see 9 I). By a computer experiment, we have found some other representations of the braid group B,, on the free groups which, in the same way as above, give group invariants of links. We will study these group invariants in this paper. In 9: I. we describe the link group via the Artin rcprcscntation. This shows the motivation of our computer expcrimcnt. The result of the cxpcrimcnt is given in $2. WC will analyze the group invariants obtained by this method in the following sections.
