Sure, but it would be quicker for you to generate them yourself.

He claims to be a PhD student. The request gives me reason to doubt the
claim.

 2011-05-10, 11:00 #6 ATH Einyen     Dec 2003 Denmark 1101011011102 Posts There is rougly 10600 / ln (10600) = 7.24 * 10596 primes from 1 to 600 digits. Even if we could store primenumber in just 1 bit per prime and using this newest record in harddisc density of 625 Gigabit per square inch: http://www.informationweek.com/news/...ktop/229402732 and we made a harddisc platter the size of the visible universe, lets say 13 billion light years in radius, it would still only hold 6*1067 primes. If we made more platters 1 inch apart for 13 billion lightyears in the third dimension we could get up to 3*1095 primes.

Well, ATH explained it perfectly

I wonder what the seek time would be.

Of the order of 10^10 years to an external observer stationary with respect to the center of the disk, assuming the mechanics worked at significant fraction of the speed of light. That assumption appears to be at least as plausible as assuming the disk could be made in the first place. The radial distance is of the order of 10^10 light years and the periphery can't rotate at faster than the speed of light in the reference frame of an observer stationary with respect to the center of the disk.

Of course, all this also assumes the absolute validity of special relativity.

I understood the question to be "Can somebody please give me a list of primes including one example of each which has 1 to 600 digits?".

Such a list would contain 600 entries and might begin " 2, 11, 101, 1009, 10007, 100003, ... "

The same I thought of, too.

The easiest way is like this: One prime with 300 digits and changing the digit-parameter should do the remaining.
