$ (A\cdot B\cdot C)+(\overline A\cdot\overline B\cdot\overline C)
ABC が全て 1 になるか ABC が全て 0 になれば SAT
$ (A+\overline A)_{=\top}(A+\overline B)(A+\overline C)(B+\overline A)(B+\overline B)_{=\top}(B+\overline C)(C+\overline A)(C+\overline B)(C+\overline C)_{\top}
$ (A+\overline B)(B+\overline C)(C+\overline A)(C+\overline B)(B+\overline A)(A+\overline C)
$ (a+x)(\overline a+\overline x)(b+y)(\overline b+\overline y)(c+z)(\overline c+\overline z)$ (a+y)(b+z)(c+x)(c+y)(b+x)(a+z)
