Now, we calculate the vertical numerical values of the columns of dots, and
enter them underneath the grid. Each vertical column (which has a maxi-
mum of 24 dots) is first divided into three groups (or two groups for super/
subscripts) of eight dots. Each group of eight dots is represented by one byte,
which consists of eight bits.
That's where the numbers down the left side of the grid come in. Notice that
there is a number for each row of dots and that each number is twice the
number below it. By making these numbers of two we can take any
combination of dots in a vertical column and assign them a unique value.
