Octadecagon Octadecagon An octadecagon (or octakaidecagon) or 18-gon is an eighteen-sided polygon. A "regular octadecagon" has a Schläfli symbol {18} and can be constructed as a quasiregular truncated enneagon, t{9}, which alternates two types of edges. As 18 = 2 × 3, a regular octadecagon cannot be constructed using a compass and straightedge. However, it is constructible using neusis, or an angle trisection with a tomahawk. The following approximate construction is very similar to that of the enneagon, as an octadecagon can be constructed as a truncated enneagon. It is also feasible with exclusive use of compass and straightedge. The "regular
The Lion has Many Ears The Lion has Many Ears Mörg eru ljónsins eyru (literally, 'Many are the Lion's Ears', or, in the publisher's translation, 'The Lion has Many Ears'), published in Reykjavík in 2010 by JPV, is an Icelandic crime novel by Þórunn Erlu-Valdimarsdóttir set between 1995 and 2009.
