The CrossPatternMatrix module supplies algebraic identities and definitions for a cross-domain pattern matrix in Recognition Science. It centers on the full turn relation tying the eight-tick octave to a complete rotation. Researchers working on periodicity and domain crossings in the phi-ladder would cite these relations. The module assembles a set of sibling definitions for squared and product terms without proofs.

claimThe full turn satisfies $2^3 times 45 = 360^circ$, with the cross pattern matrix assembled from component identities including $D_5^2$, $D_5 times 2^3$, $2^3$ squared, gap squared, and combinations such as $D^2 times$ cube and $D times$ double cube.

background

This module sits in the CrossDomain section and imports Mathlib for basic algebraic and numeric structures. It introduces definitions for matrix components built from D5 terms, the two-cube factor, and gap quantities, together with a distinctness condition on entries. These support pattern constructions that extend the eight-tick octave structure whose period is $2^3$ and the associated angular measure.

proof idea

This is a definition module, no proofs. It organizes the material as a collection of sibling declarations that enumerate the required algebraic combinations and the full-turn identity.

why it matters in Recognition Science

The module feeds cross-domain pattern results that sit above the forcing-chain steps T5 through T8. It supplies the angular closure for the eight-tick octave (T7) by equating $2^3 times 45$ to a full turn, thereby supporting later matrix constructions used in domain-interaction theorems.
