/-! ## Yang-Mills Lattice Data Size Calculations
Formalization of lattice data size calculations for Yang-Mills mass gap problem.
Based on SU(3) gauge field lattice with 64⁴ sites.
Key equations:
- Lattice sites: N = L⁴ where L = 64
- Gauge field: SU(3) = 4 complex numbers per site (link variables)
- Raw size: S_raw = N × 4 × 2 × 8 bytes
- Compressed size: S_comp = S_raw / R where R is compression ratio
