Can anyone please explain what is meant by this paragraph "Please, note that parts are not cyclic. That means that even if the tangerine division consists of only one part, but that part include more than one segment, there are two segments which were neighbouring in the initial tangerine but are not neighbouring in the division. See the explanation of example case 2 to ensure you understood that clarification"
How can one part include more than I segement ? I tried posting this as comment but it is not being posted. I don't think I was violating any rules by posting this question.
