Proposition Infinity (generally referred to as "Proposition 8"), which banned same-sex marriage in California in November 2008. The title of the episode is derived from Proposition 8, turning the 8 sideways to create the symbol for infinity (∞), hence "Proposition ∞". Though the episode satirizes arguments for same-sex marriage, it leans favorably toward the idea of allowing same-sex marriage.

Jacobi symbol that the result will become 0 or 1 instead, and won't change with subsequent terms of formula_17 (unless another error occurs and changes it back to -1). Jacobi symbol The Jacobi symbol is a generalization of the Legendre symbol. Introduced by Jacobi in 1837, it is of theoretical interest in modular arithmetic and other branches of number theory, but its main use is in computational number theory, especially primality testing and integer factorization; these in turn are important in cryptography. For any integer "a" and any positive odd integer "n", the Jacobi symbol is defined as the product of the
