octonary

Taylor also republished some of Swedenborg's work on octonary as an appendix to the above-cited publications.

The distributive adjective is octonary.

In the mid 19 century, Alfred B. Taylor concluded that "Our octonary [base 8] radix is, therefore, beyond all comparison the "best possible one" for an arithmetical system."

(The terms "binary", "ternary" and "quaternary" are from the same Latin construction, and the etymologically correct terms for "decimal" and "octal" arithmetic are "denary" and "octonary", respectively.)
