Abstract

10.1

A covering array CA_λ(N; t, k, v) is an N × k array. In every N × t subarray, each t-tuple occurs at least λ times. Then t is the strength of the coverage of interactions, k is the number of components (degree), and v is the number of symbols for each component (order). Only the case when λ = 1 is treated; the subscript is then omitted in the notation. The size N is omitted when inessential in the context.
