Abstract
For each pointed abelian group , there is an associated {\em Galkin quandle} which is an algebraic structure defined on that can be used to construct knot invariants. It is known that two finite Galkin quandles are isomorphic if and only if their associated pointed abelian groups are isomorphic. In this paper we classify all finite pointed abelian groups. We show that the number of nonisomorphic pointed abelian groups of order ( prime) is , where is the number of partitions of integer .
