Since there's an individual thread for integration there should be one for something far more challenging.
Rules:
1) Answer questions before adding more
2) Questions must have the answer(Since permutations are trivial) but write them in white as a way of checking!!
3) Non-2015ers must wait and not answer a question without giving the 2015'ers the chance...

In how many ways can he place the tigers if no cage to be left empty?
