  1. Octagon

    In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, "eight angles") is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon, t{8} is a hexadecagon, {16}. A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square.

Military Dictionary and Gazetteer

  1. octagon

    A figure or polygon that has eight equal sides, which likewise form eight equal angles. The octagon in fortification is well calculated in its ground for the construction of large towns, or for such as have the advantage of neighboring rivers, especially if the engineer can so place the bastions, that the entrances and outlets of the rivers may be in some of the curtains. By means of this disposition no person could come in or go out of the garrison without the commandant’s permission, as the sentinels must have a full view from the flanks of the neighboring bastions.
