A convex set is said to have constant width 1 if the projection of the body onto every line has length 1. It is well known that, in any dimension, the ball of diameter 1 encloses the most volume of any constant width set. A famous theorem of Lesbesgue and Blaschke asserts that the Reuleaux triangle has least area amongst any two dimensional set of constant width. In this talk, we present a few ideas that might be used to approach the minimum problem in dimension greater than two.
