All data are shown here, the current data table is here. Quote:
All bases like those are with their own page and data/history. All other bases <=3000 are listed with primes up to n=2000 in a separate file/table. Last fiddled with by kar_bon on 20200530 at 17:39

I added the second link here to the first post of this thread. I've chosen not to add some bases > 500 to the main page if they were not reserved in this thread although many that were reserved in these threads are shown. I may eventually add all your data up to base 1000.
