We study the fair division of items to agents supposing that agents can formgroups. We thus give natural generalizations of popular concepts such asenvy-freeness and Pareto efficiency to groups of fixed sizes. Groupenvy-freeness requires that no group envies another group. Group Paretoefficiency requires that no group can be made better off without another groupbe made worse off. We study these new group properties from an axiomaticviewpoint. We thus propose new fairness taxonomies that generalize existingtaxonomies. We further study near versions of these group properties asallocations for some of them may not exist. We finally give three prices ofgroup fairness between group properties for three common social welfares (i.e.utilitarian, egalitarian, and Nash).
