The Ochoa curve is the elliptic curve

3Y^2=2X^3+386X^2+256X-58195,

given in Weierstrass form as

y^2=x^3-440067x+106074110.

The complete set of 23 integer solutions (where solutions of the form (x,+/-y) are counted as a single solution) to this equation consists of (x,y)=(-761,504), (-745, 4520), (-557, 13356), (-446, 14616), (-17, 10656), (91, 8172), (227, 4228), (247, 3528), (271, 2592), (455, 200), (499, 3276), (523, 4356), (530, 4660), (599, 7576), (751, 14112), (1003, 25956), (1862, 75778), (3511, 204552), (5287, 381528), (23527, 3607272), (64507, 16382772), (100102, 31670478), and (1657891, 2134685628) (OEIS A141144 and A141145; Stroeker and de Weger 1994).
