Now let's try the following variation of the
Here we deal now with sequence of primes that grow
for the center, two digits xy at a time, 00<=xy<=99, allowing
repeated xy values.
According to the Giovanni's experience with the
previous puzzle we should expect here non-exhaustive searches,
so we must receive next Saturday only non-definitive results,
An example, provided by Dmitry Kamenetsky:
Q1. Do you think that there is a
largest solution or the sequence can be indefinitely large?
Q2. In any case, send your largest solution.
