Single Curio View: (Seek other curios for this number)
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]
