Valid and meaningful combinations are marked by the symbol (save for the length modifier columns, as described previously). Valid combinations that have no effect are labeled N/E. Using a combination marked by the symbol, using a specification not represented in the table, or using an argument of an unexpected type is undefined behavior. (See undefined behaviors 153 158, 155 160, 157 162, 158 163, 161 166, and 162 167.)
