Summary
[edit]| Description |
English: A compact packing of the plane with non-overlapping binary discs (two sizes of circles) with a radius ratio of 0.2807764064. The packing fraction (area density) is 0.93190133. This has a wallpaper group cmm. It has been shown that this structure achieves the densest possible packing at this ratio (possibly degenerately) (cited in Kennedy [1]). |
