Let 'X' be the ternary connective such that 'Xper' is logically equivalent to '(p --> 9) / (9 --> r)'. We have: p --> 9 = = | wp V a. Here, 'F' and 'T' denote the O-place connectives 'false' and true, respectively. There are some constraints. In a), show a solution with one 'F'. In b), show a solution with the letters in alphabetical order. In c), show a solution with one 'p' and the letters in alphabetical order (ignore negation). b) Using {'X', 'T'}, synthesize: p/ 9 = = | X
