contents <p>On November 11, 2025, a computational search was conducted to identify palindromic prime numbers of length 21 within the first 2 × 10^11 decimal digits of the mathematical constant π (approximately 3.141592653589793238462643383...). Using a modified C program with streaming capabilities to handle a 200 GB file containing the decimal expansion of π, one palindromic prime were discovered. </p>
