AB - The structure of the closed linear span of the Rademacher functions in the Cesàro space $Ces_{∞}$ is investigated. It is shown that every infinite-dimensional subspace of either is isomorphic to l₂ and uncomplemented in $Ces_{∞}$, or contains a subspace isomorphic to c₀ and complemented in . The situation is rather different in the p-convexification of $Ces_{∞} $ if 1 < p < ∞.
