Tangent2 (incl. note to myself):

I've been thinking/writing/advocating #PingCoincidence #PingCoincidenceLattice #PingDuration (cmp. in German "Ping-Koinzidenz" "Ping-Koinzidenz-Gitter" "Pingdauer") as basic construction or method of measurement in #Relativity implementing [Einstein's maxime](http://einsteinpapers.press.princeton.edu/vol6-trans/165?highlightText=coincidences)

[Your article](https://decomposition.al/blog/2023/01/18/enforcing-causally-ordered-message-delivery-on-the-senders-side/) uses the term "ack" ("#acknowledgement"); correspondingly #AckCoincidence #AckCoincidenceLattice
but not "AckDuration" !

Yes the tetrahedral-octahedral honeycomb can be extended "regularly"; cmp. Sierpinski tetrahedra (of any order)

But glue them "less orderly", cmp. [The Quadrahelix: A Nearly Perfect Loop](https://arxiv.org/abs/1610.00280) ...

Dodecahedra get tricky -- namely to determine by #PingCoincidence whether ambient #SpaceTime is flat, or not
