A Note on the Postage Stamp Problem
Let h, k be fixed positive integers, and let A be any set of positive integers. Let hA := {a1 + a2 + · · · + ar : ai ∈ A, r ≤ h} denote the set of all integers representable as a sum of no more than h elements of A, and let n(h, A) denote the largest integer n such that {1, 2, . . . , n} ⊆ hA. Let n(h, k) = maxA n(h, A), where the maximum is taken over all sets A with k elements. The purpose of...
متن کاملGeneralizations of the Postage Stamp Problem
The postage stamp problem and its variations are classical problems in elementary number theory. This problem involves finding the largest value that cannot be expressed as a nonnegative linear combination of two relatively prime integers m and p. It turns out that this value can be defined as a function of m and p. An original proof of this fact is the first major goal of this paper. Moreover,...

متن کاملCompact Symmetric Solutions to the Postage Stamp Problem
We derive lower and upper bounds on possible growth rates of certain sets of positive integers Ak = {1 = a1 < a2 < . . . < ak} such that all integers n ∈ {0, 1, 2, . . . , kak} can be represented as a sum of no more than k elements of Ak, with repetition.
