This has to do with web page pagination, let's say there are a lot of pages (e.g. 100) and you're on page 35 and the pagination links at the bottom of the page show:
prev | 32 | 33 | 34 | 35 | 36 | 37 | 38 | next
So three pages on either side of the page you're on, is there a specific mathematical term to describe a set of numbers like that? So far I'm calling them 'neighbors' but I just wanted to check if there was an official name.
thanks!
