Zbl
By using Dickson polynomials in several variables and Chebyshev polynomials of the second kind, we derive the explicit expression of the entries in the array defining the sequence A185095. As a result, we obtain a straightforward proof of some conjectures of Jeffery concerning this sequence and other related ones.
