The parameters 2-(2λ + 2, λ + 1, λ) are those of a residual Hadamard 2-(4λ + 3, 2λ + 1, λ) design. All 2-(2λ + 2, λ + 1, λ) designs with λ ≤ 4 are embeddable. The existence of non-embeddable Hadamard 2-designs has been determined for the cases λ = 5, λ = 6, and λ = 7. In this paper the existence of an infinite family of non-embeddable 2-(2λ + 2, λ + 1, λ)(More)
