# Preview for editing tables

In this editor you can enter or edit tables in YAML format, and you can get a preview of how numberdb would render it. You cannot save changes here. Once everything looks good, upload it to the git repository numberdb-data.

Definition
This list contains the coefficients of the $j$-invariant [1] in its $q$-expansion, $j(\tau) = \sum_{n=-1}^{\infty} a_n q^n$, where $q = e^{2\pi i\tau}$.
Parameters
$n$
—   integer ($n \geq -1$)
Programs
(P1)
Sage
numbers = {n: j_invariant_qexp(101)[n] for n in [-1..100]}
