I think you mis-coded the link for the 360 blog. There seems to be an extra http-colon-slash-slash in your link. When I removed it, the link worked fine.

Thanks for hosting!

44 is a Tribonacci number (as defined), and the Rauzy fractal is linked to these. I will probably do a longer post on Rauzy fractals at some point. However for the moment note that the three shapes are all similar and together they make a larger copy of the same shape. Thus the area of the new tile is equal to the sum of the three tiles shown. In addition the same scaling takes the smallest tile to the medium and the medium to the larger of the three. The three tiles together plus a new large and a`new medium gives the next tile up and so on. If I instead started with two square tiles I would get tiles whose areas were the Tribonacci numbers. The Rauzy fractal has the benefit that it respects shape in the scaling as well as area.

Could you give more detail on the Rauzy Fractal, and just how 44 is linked to it?

I did, many apologies.

You seem to have missed the link for Möbius strip sesquicentennial.
