Unbelievable. 4 primes within n=45 of each other!!

I think Karsten had 4 new primes in a single n=200 manual LLR reservation earlier but that was at a lower range and I think they were more spread out than this. A truly remarkable run of primes here.

What's even more amazing is that 2 of the 4 are for k=400-500, which have many more previously found primes than any other 100k range for k=400-1001.
