English version (with apologies):

Let x[0]=1/n. Compute the sequence <a[i]> for i>=0 as follows:


Is it true that n is prime iff ceil(i/(a[i]-i-1))>=n for some i?

Does ceil(i/(a[i]-i-1)) divide n for some i?

If the numerator of x[i] equals n-1 for some i, is n likely to be prime?

Just curious,

Rich Burge
