My question is related to this interesting question, but instead of looking for letters within words which happen to appear repeated three or more times in a row, I'm looking for consecutive identical sequences of letters (which could even be single ideograms in idogram-based languages such as Chinese) within words which happen to repeat three or more times consecutively within the same word.
Hypotetical examples of sought words (the parts in round brackets are optional and of arbitrary length if present):
A word having the hypothetical form "(qrstuv)abcabcabc(wxyz)".
A word having the hypothetical form "(阿比西)拉拉拉(马巴计)" [read: (ābǐxī)lālālā(mǎbājì)]. As most Chinese words are two, three, or at most four characters long, and repeated idiograms tend to come in pairs, I don't think this is possible in Chinese, but you never know, perhaps some esoteric example or an example given in some other archaic ideogrammatic language may fit the pattern! :-)
