Fair enough. This was an unnecessary side tangent.

That’s the point most westerners seem to miss. There are so many ways to use fingers to count, while the one common in Europe the simplest one possible. It’s like demo version, while some other countries get the full pro ultra max edition.

Yeah, that should work. If you stick with the definition provided by OP, “small buildings” would be technically allowed as well.

If the gasp are a problem, you could go with alternate pentagons too.

Another thing about the initial conditions. OP defined that there would be only three way intersections, but that’s clearly not the case here.

What do you intend to do with the gaps then?

The whole concept of even having a middle finger is a bit arbitrary. When you put your hands on a table, all 10 fingers spread out, the gap between the hands is the exact middle. If you include all 10 fingers, there is no middle finger, but there is a middle gap.

Andy why do we even count the fleshy fingers, when we could be counting the gaps between them? It’s the number of gaps that really matters when you’re holding on to a bunch of things like papers, magazines, forks, sticks, stones, strings, cables or whatever.
