Given the lottery of who lives where and who sees what first, you were one of the four I expected to first crack it.
It was obvious that a product of repunits was involved: besides what I wrote in my other responses in this thread, the frequency of high powers of some primes were a strong pointer.
But Clive, did you stop at the 111th because of: (a) intuition / promised economy, or (b) consideration of the powers of some of the prime factors, or (c) the "just over 6100 decimal digits", or (d) the absence of 73765755896403138401 or 119968369144846370226083377 from the factors (and if so, how did you rule it most likely that *consecutive* repunits were being multiplied?), or .. ?
