Snaefell Wheel was started to restore the wheel to its home in Laxey and on 20 August 2006, the wheel had its official reopening ceremony and began turning for the first time in decades. To mark the occasion of the official opening, and in similarity to its big sister, a piece of music "Snaefell Wheel March" was specially written by Paul Dunderdale for the occasion and performed for the first time by Onchan Silver Band at the opening ceremony, with suitable fanfare. Snaefell Wheel The Snaefell Wheel (also known as Lady Evelyn) is a waterwheel in Laxey, Isle of Man. The wheel
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
