[seqfan] Re: Use of Easy keyword

I would say it depends on how big the numbers being factored are. If  
you can generate the first hundred terms without factoring anything 
bigger than a million or a billion or so, then "easy" is legitimate. If 
you have to factor 30+ digit numbers just to fill three lines in the 
database, it should not be marked as easy.

Seqfans,

I keep running across sequences in OEIS with simple
descriptions or definitions but which, in one way
or another, depend on factorization of n. The problem
of factorization is still hard (or intractable) for
arbitrarily large n, but many of these sequences have
been given the EASY keyword which seems to be a bit
misleading. Should this keyword be dropped for such
sequences?
