Combinatorics problem. how many permutations of the set [n] are there in which no internal entry is larger that both of its neighbors? (internal = not at the end points) [n] = {1, 2, n-1, n}
can i use the equation:
k! (n-k)! to solve this? i'm not sure how to show the internal entry part of the problem
