Message-ID: <1290@stolaf.UUCP> Date: Thu, 12-Jan-84 17:34:23 EST Article-I.D.: stolaf.1290 Posted: Thu Jan 12 17:34:23 1984 Date-Received: Sat, 14-Jan-84 07:31:56 EST Organization: St. Olaf College, Northfield MN Lines: 11 We are working on a sphere-packing problem and are trying to find the volume of the gaps formed when spheres are packed together in their optimal way. We are running up against a wall and if anyone could offer some suggestions as to how to solve the following sub-problem, it would help us a great deal: What is the volume of the intersection of a sphere of radius one and a regular tetrahedron with a vertex at the center of the sphere? (The tetrahedron can be considered to be very large.)
