This study examines the integer solutions of Norm Form Diophantine equation which have quadratic curve formula and their properties. With a particular modular arithmetic on the set of solutions of NFD, many impressive mathematical facts were discovered, such as the cyclic formation or recurrence formula among the solutions, and the generator of a group made with the solutions. First, we did a study with separating the circumstances by the shape of the graph, which depends on the value of discriminant. When the graph is an ellipse, the number of integer solutions of NFD is one of 2, 4, and 6, depending on the discriminant. Also the exponentiation of the generator cycles in a fixed direction. Additionally, the tetragon or hexagon made from the solutions has a constant area, and the area of the ellipse is described in the term of the discriminant. When the graph of NFD is a conjugate hyperbola, we clarified that solutions of equations with the equal value of discriminant have a particular relationship, by comparing the generators and their exponentiation. It is well known how to find the solution of each equation, but revealing that there is a special connection among the solutions of equations with the same discriminant is one of the major accomplishment of this study.
