Extract

In the recent Gazette [1], John Sharp has given us a most entertaining account of the number η (eta) which is the only real root of the equation x3 - x2 - x - 1 = 0 , and its connection with the snub cube. I have been investigating this a bit further, with some results that may be of interest.
