Re: [PrimeNumbers] list of bases in which 1st titanic and prime S-W coincide
- The 'at some point' is now! This is nice! Running a program now that only lists bases in which the first non-trivial analogue Smarandache-Wellin prime is also the first titanic with record close to 10^999 indicated by log base 10 in addition, the output so far is

>Unless somebody gives me reason to stop ("I am going to get further along quicker than you"); I will continue running the base-23 search that becomes less and less likely to pan out (one PARI/GP window), and I will run the same question as here for gigantic as opposed to titanic. If anyone feels this should be in OEIS, btw, go ahead. My name-mention not necessary.
