Special identity for Novikov-Jordan algebras
A commutative algebra with identity (a*b)*(c*d)
-(a*d)*(c*b) = (a,b,c)*d - (a,d,c)*b is called Novikov-Jordan.
Example: K[x] under multiplication a*b = \partial(ab) is
Novikov-Jordan. Special identity for Novikov-Jordan algebras of degree
5 is constructed. Free Novikov Jordan algebras with q generators are
exceptional for any q greater than or equal to 1.
