[math-fun] sunflowers have no holes (answering Propp)

sure, one can prove sunflowers contain no large vacant disks because of theorems already mentioned/cited (Ravenstein cited/mentioned) on Weyl sequence max gaps always being small. Similarly, sunflowers contain no disks with point density greater than some constant... at least for those based on quadratic-irrational angles and for disks containing at least 2 points.
