A081119: Number of integral solutions to
Mordell’s equation .

{ 5, 2, 2, 2, 2, 0, 0, 7, 10, 2, ... }
Mordell’s equation has a finite number of integral solutions for all nonzero
. For example, for
, there are five solutions:
(2, –3), (0, –1), (–1, 0), (0, 1) and
(2, 3). For
to
5, there are just two solutions each and none for
or
7.
