[seqfan] Re: easy and bref

[Alonso Del Arte]

Those who know French or Latin might be able to help with some sequences
having keywords easy, more and word. Yesterday I knocked more off such a
sequence dealing with Portuguese (even though I don't know Portuguese)
because it seemed to me that given how big the terms presently in the
sequence are, larger terms would run into questions of non-standard names
for larger numbers.
