For
n=26 gives the highest prime for for n ≤ 4000.
]]>I haven't tried it yet but for
n=26 gives the highest prime for n≤ 8000
]]>How far have you gone with that one?
]]>I have done with the calculation for

]]>Sorry there is a mistake with the minus sign, I've edited it. Basically 1-2-3-..n=2-(1+2+3) and 1*2*..n=n!, the first equation is the generalize equation for the primes.
]]>What is the first equation for?
