Math. [irreg. f. SYZYGY + -ANT, after invariant, etc.] (See quots.)
1882. Sylvester, in Amer. Jrnl. Math., V. 87. Irreducible syzygants and irreducible invariantive derivatives of the same type, to the same quantic cannot coëxist.
1882. Hammond, in Amer. Jrnl. Math., V. 221.
1885. Cayley, Math. Papers, XII. 250. seminvariant may be expressible as a sum of products (of a higher degree) of perpetuants of lower degrees, and of perpetuants of lower degrees, and it is not on this account reducible: a seminvariant so expressible is said to be a ‘syzygant.’
