Interesting stuff. I wan’t aware of the 12-straight model.
Mathematically, I can see this works because of two things:
1. The two curves at either end do the job of a thirteenth straight aligned on
this diagonal. 2. The result is a 5-12-13 triangle, which works because the
angle of the hypoteneuse (22.62°) is close enough to the run-out from a lego
curve (22.5°) to work.
Are there any other mathematical tricks that can be used?
