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 a group groups if there exists an algorithm that, given a finite presentation of a group from the class, computes the rank of that group. The rank problem is one of the harder algorithmic problems studied in group theory and relatively little is known about it. Known results include: The rank of a finitely generated group "G" can be equivalently defined as the smallest cardinality of a set "X" such that there exists an onto homomorphism "F"("X") → "G", where "F"("X") is the free group with free basis "X". There is a dual notion of co-rank of a finitely generated group "G"
