Abstract

The discriminant of a quaternary cubic form, of degree 32 in the coefficients, was obtained as a polynomial in four invariants of the form by Salmon (1861 "Phil. Trans. R. Soc." 150, 229-239). There appears to be an incorrect numerical multiplier and the error has persisted through the several editions of his treatise. This paper offers a correction.
