It would be nice to see the statistics: what is the distribution of aliquot sequences lengths before they reach 20 digits the first time, 30 digits the first time, and so on. My impression is, if we extend all the sequences below 1 million (or three million) to 200 digits, we will have many more sequences of length bigger than 10000.

In your dreams (beside of trivial cases where you start with ~10k digits numbers, etc).

Here are several milestones which were recently (and not so recently) achieved:
  • All sequences below 1e6 reach 141 digits at least once.
  • All sequences below 1e5 reach 147 digits at least once.
  • One sequence (4788) reaches 220 digits.

Apart from that, there are only two sequences below 1e5 that have not reached 150 digits yet: 29640 and 77392.
