This article is inspired by [http://mathigon.org/almanac this] article, which was biased towards decimal properties and did not mention imaginary numbers. This article, instead, is biased towards septenary and tetradecimal properties, though the numbers are written in decimal. [[Shidinn language|Shidinn]]-related entries are also welcome.
