Is it possible to fetch id's 75, 76 and 77 if all I know is the stamp value of id 76?

Basically I need some SQL that pulls three rows based on a known stamp value plus the nearest higher stamp value and the nearest lower stamp value. It's entirely possible that id 82 could contain a stamp value that is lower than that of id 81.
