Snaefell Wheel Snaefell Wheel The Snaefell Wheel (also known as Lady Evelyn) is a waterwheel in Laxey, Isle of Man. The wheel stands in the washing floors in Laxey Glen Gardens, approximately 700 metres south of the larger Laxey Wheel. The wheel was unveiled with the name "Lady Evelyn" to mark the extensive work of Evelyn Jones in her support of the Laxey Mines Research Team. The wheel was purchased by the Snaefell Mining Company in 1865. Built by Messrs Leigh and Gilbert Howell of the Hawarden iron works in Flintshire, north Wales, it was one of two identical 50 ft (15.24
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
