The module introduces the cyclic group of order 8 as the discrete foundation for abstract harmonic analysis derived from Recognition Science. It defines locally compact groups and certifies the setup on this group. The central fact equates the group order to 2 cubed, matching the eight-tick octave. Number theorists and physicists working on discrete symmetries cite these objects. The module consists of definitions and cardinality lemmas.

claimThe cyclic group satisfies $|G| = 8 = 2^3$ where $G = ℤ/8ℤ$, providing the discrete structure for abstract harmonic analysis in Recognition Science.

background

Recognition Science realizes the eight-tick octave (period 2^3) via a finite cyclic group. The module imports Mathlib and defines LCGroup as a locally compact group together with lcGroupCount and z8Size to establish the cardinality. AbstractHarmonicAnalysisCert then certifies the harmonic analysis construction on this group. The module doc states that ℤ/8ℤ has 8 elements equal to 2^3.

proof idea

This is a definition module, no proofs.

why it matters in Recognition Science

The module supplies the group of order 8 for the eight-tick octave step in the forcing chain. It feeds the certification used by downstream results on harmonic analysis and the derivation of spatial dimensions.
