We consider relational periods, where the relation is a compatibility relation on words induced by a relation on letters. We prove a variant of the theorem of Fine and Wilf for a (pure) period and a relational period.
Mathematics Subject Classification: 68R15
Key words: Period / partial word / compatibility / Fine / Wilf.
