Table 2TC insulating materials for SGs191 and 194.

These SGs all own the same strong SI factor group, ℤ_{12}, but with different other weak SI factor groups. The numbers in the parenthesis following the name of material are the nonvanishing SI in the corresponding X_{BS}. The SI is obtained by q_{i}C_{i} mod C_{i}, where a_{i} has a common factor larger than 1, which corresponds to the subscript of the factor groups of X_{BS}. The blue color denotes the materials carefully discussed in this work.
