WebAny nilpotent CW-space can be localized at primes in a similar way to the localization of a ring at a prime number. For a collection P of prime numbers which may be empty and a localization X P of a nilpotent CW-space X at P , we let C ( X ) and C ( X P ) be the cardinalities of the sets of all homotopy comultiplications on X and X P , respectively.
