Davison Székelyhidi, László In his paper the author shows that Chebyshev polynomials of the first kind show up in relation with d’Alembert’s functional equation. Here we point out a similar property of Chebyshev polynomials concerning the square norm equation and we exhibit that the reason is due to close relations with hypergroups.

It is shown that the group $ (g, S)$ generated by $S$ and a single diffeomorphism $g$ outside $S$ has an orbit which is dense in $(E_n)^{n+1}$.
