Comments

Infinite? Periodic? It seems the answers are "Yes and No" because many numbers (such as "tenth") have multiple T's and moreover, in many of these, the T's are spread such that at least one of them will be != 2 mod 14 (2 is important because "second" is the only T-less word)

Is this the same as A091387? - R. J. Mathar, Aug 27 2025
