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.

 2021-08-09, 11:12 #257 Drdmitry     Nov 2011 23·3·11 Posts 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.
