The first one says that a sequence of integers $\\{h_n\\}_{n\\geq 0}$\r\nis an elliptic divisibility sequence if it verifies the recurrence relation\r\n$h_{m+n}h_{m-n}h_{r}^2=h_{m+r}h_{m-r}h_{n}^2-h_{n+r}h_{n-r}h_{m}^2$ for every\r\nnatural number $m\\geq n\\geq r$. The second definition says that a sequence of\r\nintegers $\\{\\beta_n\\}_{n\\geq 0}$ is an elliptic divisibility sequence if it is\r\nthe sequence of the square roots (chosen with an appropriate sign) of the\r\ndenominators of the abscissas of the iterates of a point on a rational elliptic\r\ncurve. It is well-known that the two sequences are not equivalent. Hence, given\r\na sequence of the denominators $\\{\\beta_n\\}_{n\\geq 0}$, in general does not\r\nhold\r\n$\\beta_{m+n}\\beta_{m-n}\\beta_{r}^2=\\beta_{m+r}\\beta_{m-r}\\beta_{n}^2-\\beta_{n+r}\\beta_{n-r}\\beta_{m}^2$\r\nfor $m\\geq n\\geq r$.
