CHAPTER FOURTEEN
14.4 Grey Encoding Table
A brief description is enough to explain the structure of the grey coding and decoding tables
exposed in pictures 14.4 and 14.5 respectively, because of their likeness to those already examined
for the Special code . Five different digits replaced the five digits of each code group obtained
23
from the SI code as follows: one of the available options (4 to 7) shown in the left of each column
replace the first three digits of each group between 000 and 210 listed in the corresponding position
23 AUSSME, Series H5, env.11. The grey tables adopted the same principle of the Special Code’s tables, even if the SI code
was not paginated.
