Alternating repetition is a natural way to embellish a flat rectangular panel

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• Alternating repetition appears in nature where secondary repeating centers are coherent, e.g., waves and troughs, stripes and spaces.claim0.816
• Alternating Repetitionconcept0.805
  The property that living repetition is not simple repetition but alternation where a second system of centers repeats in parallel, creating counterpoint; what is really happening is oscillation, like waves
• Alternating-Repetition Transformationconcept0.783
  A transformation that generates a repeating pattern of centers while simultaneously generating a second alternating set interlocked with the first.
• Exact repetition flies in the face of the fundamental principle of unfolding.claim0.751
  Critique of modern structural repetition as contradictory to the idea that each part should be unique.
• Mirror box for tile pattern repetitionmethod0.749
  A small box with four mirrors that reflects a single tile endlessly to reveal the repeating pattern; invented by Alexander to study tile designs.
• Echoes of similar proportions and angles appear throughout any natural system due to uniform underlying processes, giving a consistent character to different parts.claim0.744
• The 20th-century concept of modular repetition was based on erroneous strands of thought and is incapable of creating living structure.claim0.741
  Historical critique that modularity is philosophically misguided and architecturally sterile.
• The very same principles (positive space, alternating repetition, powerful centers) apply at every scale, from ornament to land and building structure.claim0.734
  Universality of the geometric principles across scales.
