Shade the even entries in Pascal’s Triangle (just mod 2) and the Sierpinski Triangle literally emerges from simple addition. This is Lucas’s Theorem unfolding the hidden recursive symmetry buried inside binomial coefficients. > Binary Logic: C(n,k) is odd only if every 1-bit in k’s binary is also a 1-bit in n’s. > Fractal Convergence: Density of odd entries → 0 as rows grow, forming the classic Sierpinski gasket with Hausdorff dimension ≈1.585. > Emergent Complexity: Pure discrete combinatorics spontaneously births continuous fractal topology.
