Definition name: space_group_symbol_hermann_mauguin_extended

Property name: list of extended Hermann-Mauguin space group symbol
Description: A list of space_group_symbol_hermann_mauguin_extended items. A space_group_symbol_hermann_mauguin_extended item is a human- and machine-readable string containing the extended Hermann-Mauguin (H-M) symbol which specifies the space group of the structure in the response.
Type: list

For each chemical_formula_reduced item the following applies:
