What is the highest number of sentences a paragraph can have?

A paragraph is a group of sentences that discuss a single topic. There are no set rules on how many sentences should be in a paragraph. However, some style guides recommend that paragraphs be between 150 and 200 words long, which typically equates to 3-5 sentences. Nevertheless, some paragraphs may be a single sentence, while some others can be very long and consist of 20 or more sentences.
