Thematization:  Truth Tables (cont.)

Table 27 summarizes the thematic extensions of all propositions on two variables.
Column 4 lists the equations of form (( f^¢ , f^¢ <u, v> )) and Column 5 simplifies
these equations into the form of algebraic expressions.  (As always, "+" refers to
exclusive disjunction, and "f" should be read as "[f_i]^¢" in the body of the Table.)
