In stating the information-preserving analogue of transitivity, I have taken advantage of a common idiom in the use of order relation symbols, one that represents their logical conjunction by way of a concatenated syntax.  Thus, <math>p \le q \le r</math> means <math>p \le q ~\operatorname{and}~ q \le r.</math>  The claim that this 3-adic relation holds among the 3 propositions <math>p, q, r\!</math> is a stronger claim &mdash; holds more information &mdash; than the claim that the 2-adic relation <math>p \le r</math> holds between the 2 propositions <math>p\!</math> and <math>r.\!</math>

To study the differences between these two versions of transitivity within what is locally a familiar context, let's view the propositional forms involved as if they were elementary cellular automaton rules, resulting in the following Table.
