摘要:
Labelled cubic graphs and labelled connected cubic graphs were first counted by Read. In this paper, a new derivation of Read's recursive formulae for the numbers of these graphs is obtained by taking into account graphs which are cubic except for one or two points of degree 2. The same methods are then used to count labelled 2‐connected cubic graphs. Labelled 3‐connected cubic graphs are counted by using the partial differential equation satisfied by the exponential generating function for labelled 3‐connected graphs, which was derived in the first paper in this series. As no cubic graph is 4‐connected, these results determine the number of labelledk‐connected cubic graphs withppoints for allpandk.

摘要:
The purpose of this note is to describe those group rings that are right hereditary. The characterization necessarily involves a number of concepts from ring theory and from group theory, and we briefly review these for the benefit of the reader. From ring theory we need the following definitions. A ringRis said to be:right hereditaryif every right ideal is projective (as rightR‐module);completely reducibleifRis a finite direct product of full matrix rings over skew fields (or equivalently,Ris nonzero and every right ideal ofRis a direct summand ofR);von Neumann regularif every rightR‐module is flat (or equivalently, for each elementrofRthere exists an elementxofRsuch thatrxr=r);rightℵ0‐Noetherianif every right ideal ofRis countably generated.
