Again the "Ellan Vannin" resumed revenue service whilst further attempts were made to find a buyer. The "Ellan Vannin's" final excursion took her across to the coast lines of County Louth and County Down via Carlingford Lough on 25 June, before she left the Isle of Man for good. Finally the Directors of the Castletown Steam Navigation Company (by now in serious financial difficulties) managed to find a buyer. "Ellan Vannin" was sold to Cunard & Wilson who were acting
Table of the largest known graphs of a given diameter and maximal degree Table of the largest known graphs of a given diameter and maximal degree In graph theory, the degree diameter problem is the problem of finding the largest possible graph for a given maximum degree and diameter. The Moore bound sets limits on this, but for many years mathematicians in the field have been interested in a more precise answer. The table below gives current progress on this problem (excluding the case of degree 2, where the largest graphs are cycles with an odd number of vertices). Below is the table of the vertex numbers for the best-known graphs (as of
