At http://arxiv.org/abs/math/0401406 Jonathan Sondow gives products for e^gamma, pi/2 and e All of them of the form \prod{{F_n}^{e_n}} where F_i=\prod_{k=0}^{n}{ (k+1)^{ (-1)^{k+1}\binomial{n}{k} } } Just the exponents e_n are different. -- p=2^q-1 prime <== q>2, cosh(2^(q-2)*log(2+sqrt(3)))%p=0 Life is hard and then you die.
