Abstract.   Crussol gave a method for computing non-trivial integer solutions to the equations in the title. We show that the method can be linked to finding points on either of two possible elliptic curves, both of which have rank greater than zero.

2010 Mathematics Subject Classification.   11D09, 11Y50.

Key words and phrases.   Elliptic curve, Crussol, multigrade.
