A fluid mail contact with the Subcommittee on the Nomenclature of N-Dimensional Crystallography of the IUCr Commission on Crystallographic Nomenclature has been maintained. At the ACA meeting in Pittsburg, some of the members of the present Commission met and organized an informal short meeting to obtain the opinion of interested people on the nomenclature of N-dimensional crystallography. A general agreement could be ascertained that the adoption by the IUCr of a standard nomenclature and notation for higher-dimensional space groups at this time is premature. This opinion is shared by this Commission and was communicated in a formal letter to the Subcommitte on the Nomenclature of N-Dimensional Crystallography.
Under the support of this Commission and the sponsorship of the IUCr,
the fourth International Conference on Quasicrystals took place in St Louis
in June. A coordination of the frequency of these meetings with the more
general International Conferences on Aperiodic Crystals that the present
Commission organizes on a triennial basis could be achieved. Thus, in 1994
(18-22 September), an International Conference on Aperiodic Crystals (Aperiodic
'94) will take place in Lausanne (Switzerland) while, in 1995, Avignon
will be the site of the fifth International Conference on Quasicrystals.
The organization of Aperiodic '94 is under way and the first
announcement will be distributed in March 1993.
