V- A Constraint-Matrix Formulation of the Twin-Prime Candidate Problem

A Constraint-Matrix Formulation of the Twin-Prime Candidate Problem, with an Extension to Prime Constellations (k-Tuples) Twin primes—pairs of primes that differ by 2—are conjectured to occur infinitely often, yet no proof is currently known (Tenenbaum & Mendès France, 2000). This work proposes a structured formulation for organizing and filtering twin-prime candidates using a modular “gate” representation around multiples of six. For all twin primes beyond the exceptional pair (3,5), the pair must be expressible as . We formalize this observation as a candidate-indexing scheme and introduce a constraint matrix whose entries record periodic eliminations imposed by small prime divisors. For each prime constraint , the condition that divides either wing induces two residue classes of gate indices, , and sieve-style marking is applied to those classes only once the corresponding wing satisfies the start threshold (Riesel, 2012). The resulting matrix provides (i) a compact representation of sieve-style filtering, (ii) a natural 2D/3D visualization of candidate survival, and (iii) an extensible foundation for computational experiments and optimization-based interpretations (e.g., selecting constraint sets, measuring overlap structure). Finally, we outline how the same stripe-and-matrix construction generalizes from twin primes (a 2-tuple) to prime constellations (prime -tuples) by replacing the two wings with an admissible offset set and applying wheel-gated stripe sieving in the corresponding index space (Crandall & Pomerance, 2005). This framework does not claim a proof of infinitude; it aims to unify modular candidate generation and structured elimination into a single linear-algebraic object suitable for exploration, visualization, and algorithmic refinement.
