The number to be tested is:
1.296210659593309 (see below for 2500 digits of it).
As I mentioned in the original note, it would be interesting to see if this
number satisfies a simple polynomial of degree > 34. The simplest
polynomial I know of that it satisfies is
x^38-x^36-x^34-x^29+x^28-x^24-x^14+x^10-x^9-x^4-x^2+1
I found this during a search for polynomials with height 1, degree 38, and
Mahler measure < 1.3.
I also have a second new Salem number that would be interesting to try.
Thanks for running this!
