New Pentagons for old spaces

Recently searching for ways to pave a large courtyard* (with in-situ recycled concrete) my hits included a metafilter favourite New Pentagons (all links still work) I got so into reading the replies, I had to add a comment myself ... until re-realising it was a 2015 post from metroid baby [account disabled ] [Part of #DoublesJubilee month!]

Manna, McLoud-Mannb, von Derau 2015 Convex pentagons that admit i-block transitive tilings

There may be nineteen shapes now Rao 2017 Exhaustive search of convex pentagons which tile
the plane
, page 15, but like the Mann et al. paper I only understand the pitchurs.

A recent, $$, book citing Rao Tessellations: Mathematics, Art, and Recreation, will be my next interlaon!

* 300m² of old concrete I want to recycle into new paving, but I need a more random arrangement, or less griddy, I was looking for repeat tilings that would work with my material and aesthetic - I want it blocky, pieces are also stronger that way, and need as few cuts as possible (using a concrete saw). So this article I'm choosing from types 4, 6, 9, 10, 13.

That's not a pentagon, it's a....boat...almond....thing.

...OK, yes, five sides, it's a pentagon, but it's weird.

Ooo, Tessallations looks so interesting! I've read the previous classic, Tilings and Patterns by Grunbaum and Shephard. I highly recommend looking it up in your local library if you like fun pictures. So glad to see a fresh, more visual take on this field! Especially one with full color pictures!

Great post Unearthed! But now I'm interested to know how your courtyard turns out - the idea of cutting pentagon paving tiles out of existing concrete sounds incredible, especially if you use one of these less common shapes.
