Weba. Among groups that are normally written additively, the following are two examples of cyclic groups. 6. The integers Z are a cyclic group. Indeed, Z = h1i since each integer k = k · 1 is a multiple of 1, so k ∈ h1i and h1i = Z. Also, Z = h−1i because k = (−k)·(−1) for each k ∈ Z. 7. Zn is a cyclic group under addition with ...
