For convenience the 8 rows for a symbol have been given the octal values "1", "2", "4", "10", "20", "40", "100" and "200". As said only 64 symbols will be interpreted on te card, those are the symbols in the upper 4 rows.
The 96 column card was designed by IBM around their
EBCDIC code. So even for the positions given above that are undefined there is a precise relation with an EBCDIC code. With some specific exceptions the translation is as follows, take the eight bits of the EBCDIC code and flip the uppermost four bits when the lower four bits have value nine or less, else do not flip the uppermost bit, but flip the other three. Exceptions occur when the lower bits have value 0, 1 or 10 (the exceptions are marked with a red border in the figure above):

There is logic and there are reasons, but I will not go into that. It is also curious that these deviations are more numerous than the deviations in the 80-column card EBCDIC code.
