OBSERVATIONS ON TERNARY QUADRATIC DIOPHANTINE EQUATION - x 63 K.Lakshmi R.Someshwari Asst.Professor, Departmet of Maematics, Shrimati Idira Gadhi College,Tamil adu,idia, M.Phil Scholar, Departmet of Maematics, Shrimati Idira Gadhi College,Tamiladu,Idia, Abstract The terar quadratic homogeeous equatio represetig homogeeous coe give b x 63 is aalsed for its o-ero distict iteger poits o it. Three differet patters of iteger poits satisfig e coe uder cosideratio are obtaied. A few iterestig relatios betwee e solutios ad special umber patters, amel, Polgoal umber, Pramidal umber, Octahedral umber, Proic umber, Decagoal ad Nast umber are preseted. Also, kowig a iteger solutio satisfig e give coe, four triples of itegers geerated from e give solutio are exhibited. Kewords Terar quadratic Diophatie equatios, polgoal umber, pramidal umber, octahedral umber, proic umber, decagoal umber. Msc Subject Classificatio: D9. I. INTRODUCTION The terar quadratic Diophatie equatios offer a ulimited field for research due to eir variet [-]. For a extesive review of various problems, oe ma refer [-]. This commuicatio cocers wi et aoer iterestig terar quadratic equatio x 63 represetig a coe for determiig its ifiitel ma o-ero iteger poits. Also, a few iterestig relatios amog e solutios are preseted. NOTATIONS: P m - Pramidal umber of rak wi sie m. T m, - Polgoal umber of rak wi sie m. Pr - Proic umber of rak.
