In geometry, a near-miss Johnson solid is a strictly convex polyhedron whose faces are close to being regular polygons but some or all of which are not precisely regular. Thus, it fails to meet the definition of a Johnson solid, a polyhedron whose faces are all regular, though it "can often be physically constructed without noticing the discrepancy" between its regular and irregular faces.[1] The precise number of near-misses depends on how closely the faces of such a polyhedron are required to approximate regular polygons.
Some near-misses with high symmetry are also symmetrohedra with some truly regular polygon faces.
Some near-misses are also zonohedra.
