Quique quod is obviously prone to haplography; on the other hand, it could be a rewriting of qui quod id es, which is itself presumably a simple corruption through interchange of qui quod es id.
So this disputed word seems to be explained by the author himself in the following clause; quiqueterminus esse sufficiat==and such that it suffices to be a boundary.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "quique" in a variety of sentences. We hope that you will now be able to make sentences using this word.
