This can be done by downloading the 114 parts of the database and mining 
what you want
from it with software. I have written  Bcx ( C )  programs that do this. 
Extracting the parts takes 1
minute with a cable connection.

Here are some examples of sequences that have only one line of data by 
criterion "keyword."

Tell me which files you want or whatever you want and I will try to extract 
it and send to you
direct. Gotta lot of time! However, I woul like to just send sequence 
numbers and maybe the
definition.

Here is a great oppurtunity for some dumb sequences. :-)

I like your idea of checking short sequences for possible extension. We 
could of course do a
similar run for sequences with only <3  n < k terms  in the first row to 
narrow it down more.

The sequence list is a 'living" entity. These are just some of the things we 
can do to maintain
its vitality.

Have fun,
