A possible approach to identifying primes could be to recognise Euler's discovery H(1-[1/2)(1-[2/3])(1-[4/5])(1-[6/7]) .....=1, where H is the harmonic series, 1+(1/2) +(1/3) ... There might be a mathematical relationship between H and the product of primes without continuing to infinity. submitted by Peter L. Griffiths.
