26.40

釋曰：法智及類智，行相俱十六者，謂法智緣欲界四諦，作苦、空等十六行相。類智緣上界四諦，亦作十六行相也。

The commentary says: "Knowledge of dharmas and subsequent knowledge both have sixteen aspects": knowledge of dharmas takes the four truths of the desire realm as object, forming sixteen aspects such as suffering and emptiness. Subsequent knowledge takes the four truths of the higher realms as object, likewise forming sixteen aspects.
