Lagrange Number (Diophantine Equation)
Given a Fermat Difference Equation (a quadratic Diophantine Equation)
with
a Quadratic Surd, assign to each solution 
the Lagrange number
The product and quotient of two Lagrange numbers are also Lagrange numbers. Furthermore, every Lagrange number is aPower of the smallest Lagrange number with an integral exponent.See also Pell Equation
