For n=10 here it is a solution that is using "only" 23 guesses, which is quite good if you compare this to log2(10!)=21.79 ( proving nothing, so we could get even better than log2(n!) ). Hence there is no two different permutations of 1..10 where you give the same 23 answers. Code: P=[[3,10,6,4,8,9,2,7,5,1],\ [3,10,1,7,9,6,5,2,4,8],\ [5,3,6,2,4,10,7,8,1,9],\ [2,6,5,8,7,1,9,4,3,10],\ [8,10,3,7,1,5,4,9,6,2],\ [6,5,10,8,4,2,3,1,7,9],\ [3,8,7,2,4,5,6,10,9,1],\ [4,1,7,5,2,3,10,9,8,6],\ [8,4,10,5,1,2,3,6,7,9],\ [10,9,8,2,5,3,6,1,4,7],\ [4,9,7,2,8,6,3,1,5,10],\ [4,5,1,9,3,10,8,7,6,2],\ [3,9,7,10,4,2,5,8,6,1],\ [1,4,2,6,10,8,5,7,3,9],\ [3,4,6,9,7,1,8,10,2,5],\ [2,10,9,4,6,1,5,8,7,3],\ [1,9,8,6,5,10,7,4,3,2],\ [1,10,3,2,9,8,4,7,5,6],\ [7,3,8,4,2,10,6,5,1,9],\ [1,5,10,8,9,6,7,3,4,2],\ [7,3,5,4,6,1,9,10,2,8],\ [9,6,2,1,4,3,7,5,8,10],\ [7,2,9,8,6,1,4,10,3,5]];
