 OFFSET 1,3 COMMENTS This number is algebraic of degree 18. Sequence A073011 contains the smallest known Salem number. It is the only root r of the polynomial x^18 - x^17 + x^16 - x^15 - x^12 + x^11 - x^10 + x^9 - x^8 + x^7 - x^6 - x^3 + x^2 - x + 1 with abs(r) > 1. - Joerg Arndt, Nov 18 2012 LINKS Arkadiusz Wesolowski, Table of n, a(n) for n = 1..10000 M.
