The reviewed paper contains a description of some new orbits in the lattice of computably enumerable sets modulo different equivalence relations, extending the collection of the known orbits. It seems that all of the content of the paper is a proof of several conjectures raised by the third author in 1989 in a private communication to the first two authors.
