The non- homogeneous ternary quadratic diophantine (Equation) is analyzed for its patterns of non-zero distinct integral solutions. Various interesting relations between the solutions and special numbers namely polygonal, Pronic and Gnomonic numbers are exhibited.


Schlegel (1883) enumerated all regular honeycombs of hyperbolic spaces of three or more dimensions, having finite cells and vertex figures. Coxeter (1954) extended this enumeration to include honeycombs with infinite cells and/or infinite vertex figures, the fundamental region of the symmetry group still being finite. One of these, {4, 4, 3}, was shown to have for its vertices the points whose coordinates are proportional to the integral solutions of a quadratic Diophantine equation (Coxeter & Whitrow 1950). In the present paper, certain quadratic Diophantine equations are found whose solutions provide homogeneous coordinates for the vertices of {6, 3, 3}, {6, 3, 4}, {4, 3, 4, 3} and {3, 4, 3, 3, 3}. A method is also given for finding coordinates for the vertices of the remaining honeycombs (with finite vertex figures), and the simplest of these are listed.

The binary quadratic diophantine equationis of interest in the class number problem for real quadratic number fields and was studied in recent years by several authors (see [4], [5], [2] and the literature cited there).

In a previous paper, the second author proved that the equation [Formula: see text] had no integral solutions for prime p > 211 and (A,B,C) = 1. In the present paper, we explain how to extend this result to smaller exponents, and to the related equation [Formula: see text]

The ternary homogeneous quadratic equation given by 6z2 = 6x2 -5y2 representing a cone is analyzed for its non-zero distinct integer solutions. A few interesting relations between the solutions and special polygonal and pyramided numbers are presented. Also, given a solution, formulas for generating a sequence of solutions based on the given solutions are presented.
