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.
Rank of an abelian group Rank of an abelian group In mathematics, the rank, Prüfer rank, or torsion-free rank of an abelian group "A" is the cardinality of a maximal linearly independent subset. The rank of "A" determines the size of the largest free abelian group contained in "A". If "A" is torsion-free then it embeds into a vector space over the rational numbers of dimension rank "A". For finitely generated abelian groups, rank is a strong invariant and every such group is determined up to isomorphism by its rank and torsion subgroup. Torsion-free abelian groups of rank 1 have been completely classified. However, the
