18.122

答：第三亦一亦異雙前二，第四非一即是前異，非異即是前一故，不異前後。

Answer: The third, being both identical and distinct, doubles the previous two. For the fourth, 'not identical' is the aforementioned distinctness, and 'not distinct' is the aforementioned identity; therefore, they do not diverge from the previous and subsequent.
