Dona Strauss Abstract. A left cancellative and left amenable semigroup S satisfies the Strong Følner Condition. That is, given any finite subset H of S and any > 0, there is a finite nonempty subset F of S such that for each s ∈ H, |sF 4F| < ·|F|. This condition is

A base for a commutative semigroup ( S, +) is an indexed set 〈 xt 〉 t∈A in S such that each element x ∈ S is uniquely representable as Σ t∈Fxt where F is a finite subset of A and, if S has an identity 0, then 0 = Σ n∈Øxt. We investigate those commutative semigroups or groups which have a base. We obtain the surprising result that has a base.
