Page boy (wedding attendant) Page boy (wedding attendant) A page boy is a young male attendant at a wedding or cotillion, a social dance. This type of wedding attendant is less common than it used to be, but is still a way of including young relatives or the children of relatives and friends in a wedding. A page is often seen at British royal weddings. There may be many pages for effect at cotillions. Traditionally, page boys carry the bride's train, especially if the bride is wearing a dress with a long train. Because of the difficulty of managing the train, page boys are
Rank of an abelian group direct sum of "k" indecomposable subgroups of ranks "r", "r", ..., "r". Thus the sequence of ranks of indecomposable summands in a certain direct sum decomposition of a torsion-free abelian group of finite rank is very far from being an invariant of "A". Other surprising examples include torsion-free rank 2 groups "A" and "B" such that "A" is isomorphic to "B" if and only if "n" is divisible by "m". For abelian groups of infinite rank, there is an example of a group "K" and a subgroup "G" such that The notion of rank can be generalized for any module
