There is, up to isomorphism, a unique group of order , namely cyclic group:Z263. This follows from the fact that is prime and there is a unique isomorphism class of group of prime order, namely that of the cyclic group of prime order.
Since all the groups of order are non-trivial abelian groups, they are certainly all nilpotent groups, of nilpotency class . Alternatively, since is prime and hence is a prime power, and prime power order implies nilpotent, all groups of this order are nilpotent groups.
