Here’s one from Eric Scerri. Add period’s n (principal quantum number) to angular momentum quantum # , l ,of corresponding s, p, d or f orbital & you get this neat arrangement, preserving triads & adding 1 more. See Journal of Chemical Education article for more details.

With regard to the above table, theoretical chemist Eugen SchwarzT warns us

Indeed, the n+l rule has little meaning in chemistry. However, since the rule

occurs in all textbooks and is absorbed by all students and teachers, it will die

out only very slowly.
