Cahen's constant is a mathematical constant that arises in the study of continued fractions and is denoted by the symbol \\( C \\). It can be defined as the sum of the reciprocals of the factorials of the natural numbers, specifically: \\\[ C = \\sum_\{n=0\}^\{\\infty\} \\frac\{1\}\{n!\} \\\] This series converges to a value very close to the number \\( e \\) (the base of the natural logarithm).
