Discovered new tilings, II (02/05/2017)
In response to our results, Hindriks discovered new heptiamond tilings with windmill units and ship units. I converted those heptiamond tilings into convex pentagon tilings. Since there are those tilings with CN-units, I also created tilings with reversed CN-units. In addition, I found a new property (a new unit). The unit is (temporarily) called "big convex nonagon unit (BCN-unit)" (see Fig.02). This BCN-unit can be reversed like CN-unit. Note that BCN-unit and CN-unit are not similar. Therefore, reversed BCN-unit will change the arrangement of the tiles in the tiling. In response to my discovery, Hindriks found more patterns. I introduce those tilings below.
