A lives on an even-numbered floor but not on the floor numbered second or fourth. Only three floors are there between A and P. There is no flat empty for L and J in CASE2A so CASE2A is cancelled out. V lives on a floor below J in CASE2B so CASE2B is cancelled out. Final arrangement:
131, 132, 140, 166, 231, 356
43, 42, 41, 39, 33, 10
