![The E8 root system consists of 240 vectors in an 8-dimensional space.](https://webarchive.library.unt.edu/eot2008/20081107041218im_/http://www.nsf.gov/news/mmg/media/images/plane1_f.jpg) |
The E8 root system consists of 240 vectors in an 8-dimensional space. Those vectors are the vertices (corners) of an 8-dimensional object called the Gosset polytope 421. In the 1960s, Peter McMullen drew by hand a 2-dimensional representation of the Gosset polytope 421. This image was computer generated by John Stembridge, based on McMullen's drawing.
