SS Ellan Vannin (1854) "Ellan Vannin" proceeded across to the new pier where she was opened to the general public. The "Ben-my-Chree", which was returning to Douglas following a pleasure cruise around the Island passed close by and greeted the "Ellan Vannin" by firing two guns. The "Ellan Vannin" entered service under the command of Captain Joseph Skillicorn, an experienced mariner who prior to his appointment had been in the employ of the Isle of Man Steam Packet Company serving on the "Mona's Queen with the rank of First Officer. Mainly the "Ellan Vannin" would ply between Castletown, Isle of Man and Whitehaven, Cumberland
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
