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 to the dimension of a vector space. The main difference with the case of vector space is a presence of torsion. An element of an abelian group "A" is classified as torsion if its order is finite. The set of all torsion elements is a subgroup, called the torsion subgroup and denoted "T"("A"). A group is called torsion-free if it has no non-trivial torsion elements. The factor-group "A"/"T"("A") is the unique maximal torsion-free quotient of "A" and its rank coincides with the rank of "A". The notion of rank with analogous properties can be defined for modules over any integral
