with m sides. = Three-dimensional figurate
number of rank n with m sides. = Star number. = Rhombic Dodecahedral number of rank n. The Homogeneous cubic equation with four unknowns represented by the equation is analyzed for its patterns of non zero distinct integral solutions. Here we exhibit four different patterns. In each pattern we can find some interesting relations between the solutions and special numbers like Polygonal number, Three-Dimensional Figurate number, Star number, Rhombic Dodecahedral number etc.
1. INTRODUCTIONNumber theory, called the Queen of Mathematics, is a broad and diverse part of Mathematics that developed from the study of the integers. Diophantine equation is one of the oldest branches of Mathematics. Diophantine problems dominated most of the unsolved mathematical problems. The cubic equation offers an unlimited field of research because of their variety. This paper concerns with an interesting equation , representing a homogeneous cubic equation with four unknowns for finding its infinitely many solutions and some interesting relations between the solutions and special numbers like Polygonal number, Rhombic Dodecahedral number, Star number, Three Dimensional Figurate number. 2.
