Yes, but in 2018, I have found that these formulas were growing too fast. So , I calculated exponents much smaller here : http://plouffe.fr/Record%20100%20primes%20sequence.txt Simon Plouffe Le mer. 3 juin 2020 à 17:08, James Propp <jamespropp@gmail.com> a écrit :
I recall it being

sometime ago, someone came up with 26 primes in arith. progression. ... But what if the primes are in geometric progression instead like a(n) = { c^n } , where { } is the nearest integer.
Isn't there a famous theorem saying that with some form like { c^c^n } or {3^3^cn} or something of the kind you can get _only_ primes?
