This dataset contains the complete list of the 55.083.357 iso-edge domains in dimension 6. The data is stored in a netCDF-4 data file. For each iso-edge domain it contains 63 canonicalized 6-dimensional coordinates that represent the iso-edge domain.Furthermore, for each iso-edge domain it contains the number of neighbouring iso-edge domains. The netCDF dimensions and variables are as follows: netcdf ctype_dim6 { dimensions: number_ctype = UNLIMITED ; // (55083357 currently) n = 6 ; n_vect = 63 ; variables: int Ctype(number_ctype, n_vect, n) ; Ctype:long_name = "Ctype canonicalized coordinates" ; Ctype:units = "nondimensional" ; int nb_adjacent(number_ctype) ; nb_adjacent:long_name = "number of adjacent Ctypes" ; nb_adjacent:units = "nondimensional" ; } The data can be extracted to a human readable format using for example the ncdump utility.
