The second of an infinite sequence of primes formed by right-concatenating further instances of an identical terminating digit (in this case the terminating prime digit 3 to 10000000002065443, the latter being the second of five consecutive 17-digit primes in arithmetic progression with a common difference of 30). The third prime in this right-concatenated sequence, i.e. 10000000002065443333333333333333333333333333333333333333 differs by only a SINGLE additional identical digit! (Might primes so formed and related by a SINGLE additional digit one day be termed "Harrison Pairs"?) [Harrison]
