Pullum, G. K. (2018). Intuition and decidability in grammar and number theory. In K + K = 120: Papers dedicated to László Kálmán and András Kornai on the occasion of their 60th birthdays (pp. 1–10)."Given a CFG for English, therefore, we could use a fully general algorithm to find out (in
cubic time) whether, for example, there is a grammatical string with ofofof as a substring. (I think there probably is, but I leave the exercise of constructing one for the reader to pursue in idle moments.)"
I have constructed a sentence with three consecutive instances of of.
