There are various programs on PGS that can do it, but they operate over 100 times less efficiently that Robert Gerbicz's code which worked only up to 2^64 I am not aware of anyone who is currently looking in the area above and close to 2^64. I'm currently looking at defined offsets from multiples of primorials in the gap length 2000 to 8000 range. Last fiddled with by robert44444uk on 20190115 at 14:55

Where is the code for finding gaps above 2^{64}? Can I please take a look?

We could find the next maximal twin prime gap. That seems to be what people are doing now.

The newest prime gap project is putting Dr. Nicely's gaps on this site.

I have something different now which has a biginteger library. I wrote a short test and had it display 2^1200 in decimal. In just a key press, the screen was full. More recently, I wrote my own program to do gap searches. It has been an ongoing project performing tests, and more tests. Is it capable of going beyond 2^64? Most definitely. Is it efficient? Probably not. I have no understanding of advanced math, so I did this in such a way that I could understand what I was doing. This is where any inefficiency would begin. For someone 64 years old, I do the best I can.

What is the next prime gap project now?

Bobby, please stop doing that.
Anyway, while we're at it... @ ATH: I'd still be interested to know a bit more about your calculation above 2^{64} here: https://www.mersenneforum.org/showpo...0&postcount=69 Calculation time or throughput / specs of the PC / availability/distributability (is that a word?) of the program? Some people might be interested in taking the calculation further, even if it's rather inefficient...
