Abstract :
We give a representation for [4]3 by circles in the plane. We also show that representing the Boolean lattice B6 by 4-spheres in R5 is equivalent to placing 26 − 2 points on the unit sphere in R5 such that certain distance requirements are satisfied. As a consequence of this result, there is no symmetric embedding of B6 by 4-spheres in R5.
