Submission + - Mathematicians finally map 57-dimensional shape
Matthew Sparkes writes: "A team has mapped a 57-dimensional structure called E8 and the results take up 60 gigabytes of data. The shape, called E8 (pronounced E-eight), is a Lie group. A Norwegian mathematician invented Lie groups in the 19th century to study symmetry. A Lie group underlies objects like balls, cylinders or cones that are symmetrical when rotated by small amounts. The team solved the problem in a four-year project using a supercomputer at the University of Washington in Seattle."
