We give the generating functions, Binet’s formulas, sums formulas and some properties forthese octonions. We also present the matrix representations of the Padovan and Pell-Padovan octonions.</dc:description><dc:date>2019</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/19902</dc:identifier><dc:language>en</dc:language><dc:relation>Turkish Journal of Mathematics and Computer Science</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/19902</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
