Description: A Burr Puzzle consists of at least three rods intersecting each other at right angles. The most well-known type is the six piece burr where three sets of two rods intersect each other. This site lets you explore six piece burrs by selecting from a list of a few precalculated burrs, or by selecting six pieces of your own making--their program will calculate the possible solutions for you. Note, a Java enabled browser is required to visit some pages of this site (marked with a coffee cup image). Virtually all pages require JavaScript to properly display. Site includes background information (including definitions and some simple lemmas arising from the definitions), references (textual and web), and a feedback form.
