Abstract

Given a collection of boys and girls, when can all the girls find husbands that they know? For a subgroup H of a finite group G, are there group elements g 1,…, g n such that {g 1 H,, g n H} is the collection of left cosets and {Hg 1,…, Hg n } is the collection of right cosets of H? Given sets A 1,, A m , are there distinct elements a 1A 1,, a m A m ?
