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 "M" over an integral domain "R", as the dimension over "R", the quotient field, of the tensor product of the module with the field: It makes sense, since "R" is a field, and thus any module (or, to be more specific, vector space) over it is free. It is a generalization, since any abelian group is a module over the integers. It easily follows that the dimension of the product over Q is the cardinality of maximal linearly independent subset, since for any torsion element x and any rational q Rank of an abelian group In mathematics, the rank, Prüfer
