Abstract
The hierarchy of conformally coupled scalars with the increasing scaling dimensions , connected with the -th Euler density in the corresponding space-time dimensions is proposed. The corresponding conformal invariant Lagrangian with the -th power of Laplacian for the already known cases is reviewed, and the subsequent case of is completely constructed and analyzed.
