Abstract

We consider circle packings in the plane with circles of sizes 11, r0.834r\simeq 0.834 and s0.651s\simeq 0.651. These sizes are algebraic numbers which allow a compact packing, that is, a packing in which each hole is formed by three mutually tangent circles. Compact packings are believed to maximize the density when there are possible. We prove that it is indeed the case for these sizes. The proof should be generalizable to other sizes which allow compact packings and is a first step towards a general result.
