This is excluded by the computer analysis. When a decision has to be taken for pearls which seem to be similar in many aspects i.e. whether or not they belong to an already defined group, or do they form a separate type by themselves - then the maximum distance value of 2,3 of the computerized analysis is of great help. If the pearls under examination are more distant from one another, or from the already defined types, then they represent a new type. An indication of the limited applicability of the mathematical method is the fact that pearls falling within the maximum limit distance of 2,3 are not necessarily always of the same type either. The reason for this is that when forming types of pearls the form was acknowledged as a decisive factor. (This could not have been avoided as the concept of types was to be retained for the pearls.) Therefore the divergence of the other features was only considered when forming the category types. This means that two pearls witlün the maximum distance of 23 belong to the same type only when they have the same form. An archeological data base can be elaborated with the codes describing the pearls.
