[seqfan] Re Number of real roots of polynomial with coefficients +-1, or 0, +-1

[Neil Sloane]

OK, I added the third sequence to go along with A282691 and A282692: see
A282701. I guess this is probably what Oanh had in mind
when we started this discussion.  I put down a guess for the initial
entries, hoping that Chai Wah or Edwin or Luca will correct them if
necessary, and also extend them!

Best regards
Neil
