Hi, Gerson !

I'm truly glad to get your always valuable contributions to one of my S&SMC's, as in the good old times. A few comments:

Why only 6 ? Not being versed in RPL I don't fully understand your code but I also don't see any reference to the maximum degree for the polynomials, which should be 8.

'X^4.+-1.*X^3.+0.*X^2.-1.'           1.3802775691 
'X^5.+-1.*X^4.+-1.*X^3.+X^2.-1.'     1.44326879127 
'X^6.+-1.*X^5.+-1.*X^4.+X^2.-1.'     1.50159480354 
'X^7.+-1.*X^6.+-1.*X^5.+X^2.-1.'     1.54521564973 
'X^8.+-1.*X^7.+-1.*X^6.+X^2.-1.'     1.57367896839

Also, even within this limited range, your program is missing two constants, one between 1.50.. and 1.54.. and another between 1.54.. and 1.57.., perhaps due to the typo that J-F pointed out (which I duly corrected) about the coefficients being -1, 0, or +1 (the '0' was missing in my OP).

Thnaks for your continued interest and best regards.
