SS Ellan Vannin (1854) her general exterior being similar to the "Countess of Ellesmere." In fact she was built very much after the model of that vessel, but with the additional requirements to adapt her for sea-going purposes in the challenging conditions around the Isle of Man. Clinker built, "Ellan Vannin" was rigged as a two mast steamer with two white painted funnels and with a full length female figurehead sitting on a rock adorned with a castellated crown. "Ellan Vannin" was well appointed for the carriage of passengers with accommodation for 91 First Class and 195 Second Class. Her after saloon was in
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
