Problem

There are again some adventurers standing in a queue to see a dragon’s treasure. This time, there are more of them – \(26\). The rules have changed slightly, they still enter exactly in the order they are queuing, but they now have to divide themselves into \(5\) groups, and some of the groups can be empty, do not consist of any adventurers at all. In how many ways can they do that now?
