unrepeating
Happens only once
Unrepeating describes something that doesn't repeat or recur—a pattern, sequence, or event that happens only once or varies continuously without cycling back: The decimal expansion of pi is infinite and unrepeating.
Often used in mathematics for non-terminating decimals that never settle into a recurring pattern, or more broadly for anything deliberately varied: an unrepeating playlist.
