[seqfan] Re: In search of prime concatenations of successive values of A006512 Greater of twin primes

[Douglas McNeil]

I think the concatenation of the first 64 upper twin primes:

5713193143617310310913915118119319922924127128331334942143346352357160161964366181182382985988310211033105110631093115312311279129113031321142914531483148916091621166916991723178918731879193319511999202920832089

is prime.
