This is what paper says: "We collected data from 8000 aliquot sequences: eight sets of 1000 sequences, with
each sequence starting at 2^{16+32n} + 2k, where 0 ≤ n ≤ 7 and 0 ≤ k < 1000."

It reach the length of 9359 with C153 fully ECM'd by aliqueit. If anyone wants to try luck and extend it a bit more, go ahead.

You can check that 26236:i3 coincides with 4800:i7.Therefore the open sequence which started from 26236 is the same as 4800.
