Abstract
Any classification describes some structure of taxons on a subject field. Thus, one of the natural aspects of a classification theory is the study of possible taxon structure types. In particular, two classifications generating isomorphic taxon structures (regardless of size or how filled they are) could quite rightly be said to be of the same type. Let us formulate this situation in precise terms. Assume M is the subject field of the classification (the class of all objects to be classified). We use T to denote the set of taxon subclasses identified by the classificational features. On taxon set T the is a natural order of inclusion
