| Dec 30, 2023 at 23:22 | comment | added | joriki | The reference for $\neg(43\Rightarrow93)$ is on p. $341$ of Howard & Rubin (which, by the way, can be borrowed here). (I posted these as comments because they don't answer your question; I just thought they might be of interest.) | |
| Dec 30, 2023 at 23:22 | comment | added | joriki | An implication table for Howard & Rubin is here. The codes are explained here. The entry for $367\Rightarrow6$ is $0$: "The status of the implication is unknown." As the Herrlich models show, $\neg(6\Rightarrow367)$; this can be traced to $43\Rightarrow8\Rightarrow94\Rightarrow6$, $367\Rightarrow366\Rightarrow93$ and $\neg(43\Rightarrow93)$. | |
