# Talk:Tribonacci number

This article and the closely related Tribonacci sequence are both short and so closely related that it seems sensible to merge them. It would also be a good idea to mention that the mysterious $\rho,\sigma,\bar\sigma$ are the roots of the companion polynomial $z^3 = z^2 + z + 1$. Richard Pinch (talk) 08:54, 22 March 2018 (CET)
