It seems to be the same kind of periodicity unless I'm missing something.
> Periodicity, for our purposes, is a repetition of relationships in specific intervals. Mendeleev had found that the elements were periodic based on the relationship between atomic weight and valency.

- shoxidizer 5mo agoYeah, they're both about periodic repetition. But a periodic tiling repeats in its entirety, exactly, with a fixed period. The periodic table groups elements based on properties that repeat periodically, but the periods change as you move down the table. The tiling also has string of repeating patterns, like the elements, but a periodic tiling is something other than just that.
- indoordin0saur 5mo ago> but the periods change as you move down the table Sounds like the periodic table is already aperiodic.
- xigoi 5mo agoIndeed, it’s not periodic in the strict mathematical sense.
