Queen to receive four-dimensional shape
The Queen is to be presented with a mathematical shape by an Oxford University professor.
Professor Marcus du Sautoy has named a new symmetrical shape to honour the Queen's Diamond Jubilee.
The new shape encodes three numbers in its contours, 1952 - the year of the Queen's accession to the throne, 2012 and 60, the number of years she has reigned.
He will present the Queen with a certificate describing the Diamond Jubilee Group in mathematical language.
