A special lexicon is given for the interpretation in the group (I, II, IV, D)* of the linear axioms of congruence of Euclidian geometry, and a solution is presented of the problem: under which conditions do these axioms hold true in the group under discussion. The concept of «elliptical systems of crts* is introduced.
