Default New results on factoring 2^2187+1

A few days ago, I have finally found how to find new factors using Prime95 without re-finding old ones, and I have found a new prime factor of c400 (previously the only factor not yet fully factorized), which is 6326666886932800988419273258756815291776881. Thus, the composite factor is now reduced to c357. (It seems that I have made a mistake in one of my previous thread, since I tend to mix up 2187(3^7) and 2197(13^3) quite often.)
