{This key controls how group numbering is displayed:
\vspace{4pt}\begin{itemlist}
\item\red{\textbf{arabic}}: group numbers are shown in arabic numerals as recommended by IUPAC since 1988.
\item\red{\textbf{CAS}}: group numbers are shown in Roman numerals and `A' or `B' suffix. This is an older naming scheme, used by the Chemical Abstract Service (CAS), more popular in the United States.
\item\red{\textbf{IUPAC}}: group numbers are shown in Roman numerals and `A' or `B' suffix. This is an older naming scheme, used by IUPAC before 1988, more popular in Europe.
\item\red{\textbf{CAS*}}: combines the option \red{CAS} and \red{arabic}. Roman numerals and `A' or `B' suffix are above the group and the arabic numerals above them.
\item\red{\textbf{IUPAC*}}: combines the option \red{IUPAC} and \red{arabic}. Roman numerals and `A' or `B' suffix are above the group and the arabic numerals above them.
\item USER DEFINED LIST: a comma separated list with groups labels. The list can be of any size, and the labels will be set in the order in which they appear. \textit{If less than eighteen labels are provided, the remaining groups will have no label. In the same way, if more than eighteen labels are provided, only the first eighteen will be used}.
