Production of ensembles of alpha particle triples associated with the Hoyle state (the second excited state 0{sub 2}{sup +} of the {sup 1}2C nucleus) in peripheral dissociation of relativistic {sup 1}2C nuclei is studied. Stacks of nuclear track emulsion pellicles exposed to {sup 1}2C with an energy from hundreds MeV to a few GeV per nucleon serve as the material for studies. The Hoyle state decays are reconstructed via measurement of emission angles of α particles with the precision sufficient for identification of the unstable {sup 8}Be nucleus. The role of alpha particle bonds corresponding to {sup 8}Be in the Hoyle state is determined.
