โœฆ Synopsis


Given any three permutations on { 1, . . , n}, we want to choose f : { 1, . . . , n} + { -1, 1) so that the maximum absolute partial sum off values over the permutations is minimized. The three-permutations problem is to determine the supremum of this minimum taken over all n and all triples of permutations on {l, , n}. The only thing presently known about the supremum is that it is at least two. This paper establishes a result for a restricted case of the problem in which the maximum absolute partial sum for one of the three permutations equals 1. The supremum in this case is unbounded.

The game of 'Mousetrap, a problem in permutations, first introduced by Arthur Cayley in 1857 and independently addressed by Cayley and Adolph Steen in 1878, has been largely unexamined since. The game involves permutations of \(n\) cards numbered consecutively from 1 to \(n\). The cards are laid out
