### Description (last modified by )

Method to construct finitely generated abelian groups as quotients of free groups. User inputs a list of integers to define an abelian group, then the invariants of the input list are used to build the group as a finite presentation.

sage:groups.presentation.FGAbelian([2,2]) Finitely presented group < a, b | a^2, b^2, a^-1*b^-1*a*b > sage: groups.presentation.FGAbelian([6,3,5,17]) Finitely presented group < a, b | a^3, b^510, a^-1*b^-1*a*b >
