%0 Journal Article %T Mean Width of a Regular Simplex %A Steven R. Finch %J Mathematics %D 2011 %I arXiv %X The mean width is a measure on n-dimensional convex bodies. An integral formula for the mean width of a regular n-simplex appeared in the electrical engineering literature in 1997. As a consequence, expressions for the expected range of a sample of n+1 normally distributed variables, for n<=6, carry over to widths of regular n-simplices. As another consequence, precise asymptotics for the mean width become available as n->infty. %U http://arxiv.org/abs/1111.4976v1
