$$\alpha_{0} = \left(-1 + \sqrt{17}\right)/2$$ $$\alpha_{1} = \left(-1 - \sqrt{17}\right)/2$$ $$\beta_{0} = \left(\alpha_{0} + \sqrt{\alpha_{0}^2 +4}\right)/2$$ $$\beta_{1} = \left(\alpha_{1} + \sqrt{\alpha_{1}^2 +4}\right)/2$$ $$\gamma_{0} = \left(\beta_{0} + \sqrt{\beta_{0}^2 - 4\beta_{1}}\right)/2$$ $$\delta_{0} = \left(\gamma_{0} + \sqrt{\gamma_{0}^2 - 4}\right)/2$$ $$\delta_{0}^{17} = 1$$
