Peirce’s 1870 “Logic of Relatives” • Comment 8.5

All,
I'm breaking the email version of this Comment into sections
on account of the abundance of Figures and attachments in it.
[Section 1]
Since multiplication by a dyadic relative term is a logical analogue
of matrix multiplication in linear algebra, all the products computed
above can be represented by “logical matrices”, that is, by arrays of
boolean {0, 1} coordinate values. Absolute terms and dyadic relatives
are represented as 1-dimensional and 2-dimensional arrays, respectively.
The equations defining the absolute terms are given again below,
first as logical sums of individual terms and then as n-tuples
of boolean coordinates.

Since we are going to be regarding these tuples as column arrays,
it is convenient to arrange them into a table of the following form.

Here are the dyadic relative terms again, followed by their
representation as coefficient matrices, in this case bordered
by row and column labels to remind us what the coefficient values
are meant to signify.
