Ralph Griswold explains how term-replication sequences, in which each term of a base sequence is repeated according to a replication function, can generate weaving patterns. He describes the notation, value-based, position-based and combined replication functions, and sequences that supply the replication factors separately. Examples use the positive integers, primes, Fibonacci numbers and the Morse-Thue sequence as base sequences. Appendices give pattern drawdowns, plain and mirrored, made with tabby tie-ups and labeled by their sequence formulas. The patterns may suit profile drafting as block patterns rather than direct interlacement.
