comment: Cremona label 58a1.
Definition
Let $E/\mathbb{Q}$ be the reduced global minimal Weierstrass model recovered from $(c_4,c_6)$ by Formula (1), and let $P=(x_P,y_P)$ be an integral nontorsion point on $E$. The entry is $W_n(P)=\psi_n(P)$, with $\psi_n$ the $n$-th division polynomial.
Parameters
$N$
—   conductor of $E$ ($N\geq1$)
$c_4$
—   invariant $c_4$ of the reduced global minimal model of $E$
$c_6$
—   invariant $c_6$ of the reduced global minimal model of $E$
$x_P$
—   $x$-coordinate of $P$
$y_P$
—   $y$-coordinate of $P$
$n$
—   sequence index ($n\geq1$)
Formulas
(1)
For the reduced models in this table, $b_2$ is the unique element of $\{-4,-3,0,1,4,5\}$ with $b_2\equiv -c_6\pmod{12}$, $b_4=(b_2^2-c_4)/24$, and $b_6=(-c_6-b_2^3+36b_2b_4)/216$. The model has $a_1\equiv b_2\pmod 2$, $a_3\equiv b_6\pmod 2$ with $a_1,a_3\in\{0,1\}$ and $a_2\in\{-1,0,1\}$, and $a_2=(b_2-a_1^2)/4$, $a_4=(b_4-a_1a_3)/2$ and $a_6=(b_6-a_3^2)/4$.
(2)
With $W_0=0$ and $W_1=1$, the terms are a divisibility sequence: $W_m(P)\mid W_n(P)$ whenever $m\mid n$. They satisfy $W_{2m+1}=W_{m+2}W_m^3-W_{m-1}W_{m+1}^3$ for $m\geq2$, and $W_{2m}W_2=W_m(W_{m+2}W_{m-1}^2-W_{m-2}W_{m+1}^2)$ for $m\geq3$.
(3)
For $n\geq1$, $x(nP)=x(P)-W_{n-1}(P)W_{n+1}(P)/W_n(P)^2$.
Comments
(4)
This table uses the division-polynomial convention $W_n(P)=\psi_n(P)$ for elliptic divisibility sequences [1] [2]. Here $\psi_n\in\mathbb{Z}[x,y]$ is the full division polynomial, so $\psi_2=2y+a_1x+a_3$. In Sage [3], evaluate this convention with two_torsion_multiplicity=1, since the default uses two_torsion_multiplicity=2. The table does not store the denominator sequence obtained from writing $x(nP)=A_n/D_n^2$.
(5)
The curve is identified by $N$, $c_4$ and $c_6$; in Cremona's labelling [4], the five curves here are 37a1, 43a1, 53a1, 57a1 and 58a1. LMFDB [5] numbers curves within an isogeny class differently from Cremona's tables, so a label here is not an LMFDB label.
(6)
In the computed range, $P$ is the first Mordell-Weil generator returned by Sage for a rank-one curve, replaced by $-P$ when necessary so that $W_2(P)>0$.

Division polynomials $\psi_n$ of elliptic curves over $\mathbb{Q}$ —   gives the polynomials whose values at $P$ are the terms $W_n(P)$
Highest known ranks of elliptic curves over $\mathbb{Q}$ with prescribed torsion subgroup —   records rank records by rational torsion subgroup, while this table records divisibility sequences from individual nontorsion points
Regulators of elliptic curves over $\mathbb{Q}$ of rank $1$ —   uses the same $(N,c_4,c_6)$ curve index for rank-one curves and records their regulators
Data properties
Entries are of type: integer
How well the digits are known: exact
Table is complete: no (it holds $W_n(P)$ for $1\leq n\leq50$, for every rank-one curve in Sage's mini Cremona database [4] with conductor $N\leq60$, taking $P$ to be the first Mordell-Weil generator returned by Sage, negated where necessary so that $W_2(P)>0$)
Sources of data: [4]
How they were obtained:

The generator reads exact Weierstrass coefficients from Sage's mini Cremona database [4] and evaluates the exact division polynomials by the same coordinate-ring recurrences used for the division-polynomial table.

more

It verifies the elliptic divisibility sequence recurrences in Formula (2), verifies Formula (3) against exact point multiplication in Sage, and checks the first terms for 37a1, 43a1 and 53a1 against OEIS A006769 [6], A050512 [7] and A178627 [8].
