2.188

五十一卷亦為六難，意大同也。此第六、七合，是彼第六，故彼為六。有說：無此第六，彼第六者，即此第七。

Fascicle 51 also poses six challenges, and the meaning is largely the same. In that text, the sixth and seventh here are combined into its sixth, which is why it has six. Some say that there is no sixth here, and that the sixth there is precisely the seventh here.
