GS Shape Symbols

The shapes of shape blocks are intended to reveal their meaning to the reader. All GS6 shape symbols begin with a dot-5 marker that is not part of the shape. The remainder of the symbol consists of one or more prefixes followed by a root cell. The first prefix after the dot-5 must include a dot-6.

The GS8 symbol corresponding to a GS6 shape symbol is the part of the GS6 symbol after the dot-5 but dropped an additional row. Thus all GS8 symbols begin with a prefix that includes a dot-8.

In the following tables, the GS8 shape block is given first and the GS6 block is given next, each in square brackets.
