If and are sets, the set of functions from to \(often written \) is sometimes also written \. This latter notation, which I'll call exponential notation, is related to the notation for finite powers of sets \(e\.g\., for the powers of triples of elements of \) as well as the notation of exponentiation for numbers\.
I don't think this is what you mean, is it?

Thanks, I've corrected it. That was a strange typo.
