Or he didn't have time.

When you send a file, aliqueit doesn't check that it makes sense, (i.e. it doesn't check that the factors divide and the aliquot sums match up, or even that there are line numbers) it just sends it. Besides, when you don't have the whole sequence starting at 0, it can only check the portion that's there and assume the rest is correct, so even if it did check, it would pass the check.

Just back in snowy Cambridge after a rather tiring two-day trip to a customer in Kent, staying at a hotel whose promised free wifi wasn't there.

AFAIK, this is the largest aliquot sequence GNFS!

Soon to be beaten, already.
