I found an exception:
Starting from https://en.m.wikipedia.org/wiki/Help:IPA/English: Help:IPA/English > Alphabet > Letter (alphabet) > Symbol > Sign (semiotics) > Semiotics > Help:IPA/English
If you don’t think the IPA link counts as “the first link”, then
Starting from https://en.m.wikipedia.org/wiki/Japanese_language: Japanese language > Japonic languages > Japanese language
will also cause a loop.
wouldn’t count that stuff in the parenthesis, as it’s just showing the translation of “japonic lanuages” and then the transliteration of that translation. Sometimes they’ll have pronunciation or whatever in parentheses, and that shouldn’t count for the same reason.
If instead of clicking on “japanese” again, you had clicked on “language family”, you’d get all the way to philosophy in 8 or 9 clicks (i lost count and i’m too lazy to fix it).
