By the way, I don't believe that nonsense about 18091 for a moment. Being off balance like that would make my pinwheel all wobbly. Quite happy with what I've got, thank you - until the next one, that is.

*cue the violins*

I am very poor and own nothing of any monetary value, so I intend to leave my collection of pinwheel numbers to my children when I die. SURELY nobody would deprive my poor children of their inheritance!
