A. The 60 degree rhombus and itsthree 120 rotations.B. Since the cluster in A forms a regular hexagon, we may tile with that cluster.C. Each color tiles the plane by itself.D. Any two colors tile as well. If the colors are {0,1}, then the tessellations consist of all sequences in {0,1}*. That is, there are infinitely many distinct tessellations using this tile..E. We may not tile completely 'willy nilly'. Flaws (such as X) may be introduced in which no tile will fill the flaw.F. In a two color layout, we may introduce exactly n instances of the third color for any integer n ≥ 0.G. If we try to surround a given finite two color cluster with the third color, we will not succeed. Infinitely many tiles of at least one of the first two colors must be used.H. If we try to surround a given tile of one color B with only a second color T, we will not succeed. Infinitely many tiles that are not colored T must be used.
