Abstract

Compares the UDC and CC numbers given as the examples in Sec 8 of Paper B. Shows that CC gives co-extensive class numbers in all the 20 cases but UDC gives co-extensive class numbers only in five cases. As a result of mixed notation, CC secures the same degree of co-extensiveness of UDC with about two fifths the number of digits. It secures fully co-extensive calss numbers in all the cases with only two-thirds of the number of digits of UDC.
