"Fools Gold" would go on to appear on certain non-UK versions of their self-titled debut studio album (1989). "Fools Gold" became the band's biggest commercial hit at the time. It was their first single to reach the top ten of the UK Singles Chart and stayed in the top-75 for fourteen weeks, peaking at number eight. "Fools Gold"
Duocylinder flat tops. This operation is equivalent to removing select vertices/pyramids from polytopes, but since the 3-sphere is smooth/regular you have to generalize the operation. The dihedral angle between the two 3-d hypersurfaces on either side of the ridge is 90 degrees. Parallel projections of the duocylinder into 3-dimensional space and its cross-sections with 3-dimensional space both form . Perspective projections of the duocylinder form torus-like shapes with the 'doughnut hole' filled in. The duocylinder is the limiting shape of duoprisms as the number of sides in the constituent polygonal prisms approach infinity. The duoprisms therefore serve as good polytopic approximations
