Datasciency gentlemen and gentleladies, i have a question for thee.Consider the function hop(x, f, t) = "the translation of the word x from the language f into the language t". e.g. hop("burro", spanish, english) = "donkey", but also hop("burro", italian, english) = "butter" Now, the question is: is there some x so that exists a chain of hops that starts with x (e.g. hop(hop(hop(x, f1, t1), f2, t2) f3, t3) and so on) and also ends with x, that is not the banal chain that reach a fixed point (e.g. "radio" that is the same in a lot of languages) and goes back in the opposite direction? Are there more than one of such words? Chains? What is the maximum length of such chains?
