6.3.2 Boolean algebra

Problem: The table shows the numbers of sets of arguments (in lexicographic order), on which the logical function takes a value equal to one. Write this function in PDNF, PCNF, PPNF. Minimize it using the Quine method and the Karnaugh method. \begin{tabular}{|c|c|c|c|c|c|c|c|} \hline \multicolumn{1}{|c|}{ Constituent numbers } \\ \hline 2 & 3 & 6 & 7 & 8 & 14 & 15 & - \\ \hline \end{tabular}
