geodesic dome \ge`o*des"ic dome\, n.
   A domelike structure invented by R. Buckminster Fuller, in
   which straight structural parts are connected to form
   interlocking polygons, affording great strength and rigidity
   combined with light weight. The typical form has the outlines
   of the top half of an icosahedron, with the triangular spaces
   filled with structural members forming triangles, hexagons,
   and squares.
