We give Binet's Formula, Cassini's identity, Catalan's identity, d'Ocagne identity, generating functions of the hyperbolic k-Jacobsthal and k-Jacobsthal-Lucas octonions. Also, we present many properties of these octonions.</dc:description><dc:publisher>BULGARIAN ACAD SCIENCE</dc:publisher><dc:date>2022</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/16684</dc:identifier><dc:identifier>https://doi.org/10.7546/nntdm.2022.28.2.318-330</dc:identifier><dc:identifier>1310-5132</dc:identifier><dc:language>en</dc:language><dc:relation>NOTES ON NUMBER THEORY AND DISCRETE MATHEMATICS</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/16684</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
