Abstract : The categorization of sequences of two-level fractional factorial plans involving from three to nine factors is presented. The categorization is based on the lengths of the interactions in the defining contrast for each regular fractional replicate in a sequence of plans. A typical sequence of plans is presented for each category with up to six factors along with a listing of the estimable parameters and their average variances at each stage of the sequence.
