@BretDevereaux @AtienzaElias I wonder what your have to say about his take on the Dark Ages?: https://t.co/RmpqRGrG8C

@dimden @demomikke I've tried that several times and have not gotten it to work. (old pic of warning below)

The most recent post on the blog is a follow up of my re-worked non-peridoicity proof for the Turtle #aperiodic #monotile. It is rather dry, but it explains the 'even' distribution of reflected tiles in the Turtle(thus Hat) tilings and sharpens that finding.

[mathBlock(Inactive, see other accounts) @mathBlock]

@alytile It seems that you have coloured the original F metatiles white as well as the tile in the H metatile directly connected to it. However, there are a few F metatiles here that aren't coloured white. Why did you choose not to colour them the same?

The new tiles look and substitute like this:

Here's something for those still interested in the Hat or Turtle #aperiodic #monotile. If you take one of the two tiles below, place one on a plane and then try to fill the rest of the plane with Hat tiles, it seems that the position of every Hat tile is already determined.

These can also be also be modified for the Turtle tile. Using the metatiles and substitutions in these pictures...

@ZenoRogue I posted about this elsewhere, but I thought of this hyperbolic prototile thinking about the binary tile and some stuff I was working on. All lengths labelled are Euclidean apparent lengths in the half-plane representation(assuming I did it right).

If you start with a #spectre #aperiodic #monotile tiling, and just keep the oddballs, you can flip each one and smush them together to get a new tiling. However, you are left with gaps, which become the new oddballs.

@mathBlock I didn't realize I had to follow the 26 posts, so I was confused by your comment. (I am new to twitter.) Here's a version where I use the edge instead of the vertex to avoid having to extend the outlet past the boundary. And I use one decoration instead of two.

[mathBlock(Inactive, see other accounts) @mathBlock]

@AndrewR88968514 For the Hat/Turtle tiling, this edge consistency forces the 'odd'(reflected) tiles to exit the same way as the other tiles.

@AndrewR88968514 See Figure 3.1 in https://t.co/UctyHzZfP5 to see what I'm talking about with the edges.

@apu_yokai @mananself @JimPropp @robinhouston @cinderBlock_496 Sorry for the late reply. I don't think I've solved this per se, but I believe I've made progress working with Turtle tiles. See https://t.co/iQS7qJYLEu , replies, and the linked blog posts for details.

The blog post at (https://t.co/I9H0vCSN6k) has more details and further discussion. It is strongly suggested to read the previous post in the quoted/linked tweet(https://t.co/jeU9rnXFpe) first.

*Note on step 3: It may terminate w/o filling the outline if there exists a ‘loop’ of hexagons and fixed rhombs. Our example outline does not produce those, so it can be completely filled in.
