The problem of reconstruction of a regular polyhedron with integral coordinates of vertices from given edge (or a diagonal of a cube) is considered. Necessary and sufficient conditions for existence of such polyhedrons are established. Algorithm for finding a solution is presented and the number of the solutions is determined. Bibliography: 1 title.
