X+9 ? I'm not sure if that was the kind of answer you were looking for but that's what I got out of that.
The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.
