Here's a fun tiling by three types of pentagon.
Even more fun: it's derived from the spectre tiling!

@npub17nm…dm57 That's my strategy too, but I think I can't face doing major reorganisations, so I mainly do local optimisation, and the result depends heavily on the rough layout I initially chose

The most I've managed today is 80 walls.
Is today's just a tricky one for the wallmaxxers, or have I missed a better strategy?

@npub1knz…c73p I wouldn't be surprised if there were a periodic tiling using an infinite number of these stars together with spectres

It's funny and interesting that you can tile the plane with an infinite collection of spectres and one solitary 12-pointed star

This is pretty cool! Might be fun for the 3D-printing enthusiasts to play with.

Talking to ChatGPT about maths is like when you get cornered at a party by someone who is very enthusiastic about some mathematical topic that they don't understand at all. (It used to be Gödel's Theorem most of the time.)

I completed #Celtix 1 using 17 walls.

This is an exciting moment for me! The official public unveiling of a polyhedron I found a couple of years ago. Along with lots of interesting back story etc. from @npub1qvn…y7yf https://youtu.be/daVny9y72UE?si=M5ecCCQBwzWMZ60m

Is anything known about optimal packings of quarter-circles into a square?

@npub1pzy…pz3v @npub1cv8…cvxj @npub1knz…c73p I suspect one could relatively easily be more clever about programming. Has anyone tried to implement it for a GPU, for example? It feels intuitively like the sort of thing that could make good use of that style of parallel programming.

@npub1z2q…3yuf I probably would be, but sadly I'm busy with about 5 other things this week
