The exponential of the negative of a constant denoted with this letter appears in Merten’s third theorem and is related to the product over primes of “one minus one over p.” A distribution named for this letter can be written as a product of (-5[1])a Weibull distribution and a variant form of the stable count distribution. It’s not sigma, but a set of matrices named for this letter can be used to generate a representation of the Clifford Algebra. It’s not zeta, (15[1])but a function of (*) “one minus s” denoted with this letter appears in Riemann’s functional equation. That function denoted by this letter is equal to the integral from zero to infinity (10[1])of [read slowly] “t to the z minus 1 times e to the minus t dt,” and is a generalisation of the factorial function. The range of the electromagnetic spectrum with the highest energy is denoted by, (10[1])for 10 points, which third letter of the Greek alphabet? ■END■
