[seqfan] Re: Open problems

[franktaw at netscape.net]

My understanding of the "unkn" keyword is that the sequence itself is 
unknown or very poorly understood.  It doesn't mean any sequence for 
which there is an open conjecture.  I think that is an important 
categorization, and it should not be redefined.  A keyword that does 
what you (Tanya) suggest might be useful, but there are a large number 
of potential keywords in that "might be useful" category.

It certainly would be nice to have conjectures listed some place.

You should also be aware that there are some sequences where one 
comment makes a conjecture, and a later one confirms it.

A final note: to search for conjectures in the database, look for 
entries containing the words "apparently" or "appears", too.

Hello all,

Do we have a list of open problems? There are 1308 sequences containing 
the word
conjectured, but only 35 containing the keyword unkn.

It would be nice to have a list of sequences needing proofs sorted in 
order of
importance. Also, it would be nice to add the keyword to all of them.
