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 of jealousy; that Guðrún's son Svenni stole the antique pistol; that Kjartan in fact killed himself, staging his suicide as a murder (echoing how in "Laxdæla saga" Kjartan refuses to defend himself against Bolli); and that Hrefna murdered Bolli, apparently supposing that he was to blame for Kjartan's murder. In an epilogue, Guðrún bumps into Leó in the street and it becomes clear from family resemblance that her son Þorlákur is in fact not Bolli's son, but Leó's, and the two become a happy couple, echoing Guðrún Ósvifursdóttir's fourth marriage, to Þorkell Eyjólfsson, in "Laxdæla saga".
