Again.............I am generalizing.........I do realize the zeros in the imaginary part have decimals........................10 and 10............the primes in the pf..........add up to 28.........the non primes.............add up to 37................if u add 2 + 8 = 10................3 + 7 = 10.............strange.................a 15 or so year old Gauss noticed a pattern in the primes................scaled down by two........for successive powers of 10.........................

The so-called xi-function defined by Riemann has precisely the same zeros as the nontrivial zeros of with the additional benefit that is entire and is purely real and so are simpler to locate.
ZetaGrid is a distributed computing project attempting to calculate as many zeros as possible. It had reached 1029.9 billion zeros as of Feb. 18, 2005. Gourdon (2004) used an algorithm of Odlyzko and Schönhage to calculate the first zeros (Pegg 2004, Pegg and Weisstein 2004). The following table lists historical benchmarks in the number of computed zeros (Gourdon 2004).
