A Genocchi number is a particular type of integer that arises in number theory and is related to the Bernoulli numbers. Specifically, the Genocchi numbers \\(G_n\\) are defined as the integers that can be expressed through the generating function: \\\[ \\frac\{2x\}\{e^x + 1\} = \\sum_\{n=0\}^\{\\infty\} G_n \\frac\{x^n\}\{n!
