The problem, however, is as follows: there are sequences in the database 
that cannot be accessed by searching for them. For example:

-Go to <http://www.research.att.com/~njas/sequences/Seis.html#FULL>

-Scroll down to the link to Part 100.

-Note the sequence next to the link.

-Try to look up that sequence in the database. The search will not return 
any results.

Now, we know the sequence is in the database, but we cannot find it. That 
is the problem I was alluding to earlier, not the sequence A100000.

Incidentally, note that the sequence A100000 was not the 100,000th sequence 
to be added to the database. When the sequence A100000 was added, the 
database was still about 500 sequences short of 100,000. It is only in the 
last 24 hours or so that the database has actually reached 100,000 
sequences, and we have run into this problem.
