Just to see if I understand what is preserved under set forcing. Is it 
right to say that a single supercompact cardinal is not preserved under set 
forcing, since you can collapse it to smaller cardinals? But if each 
supercompact has a larger supercompact, that is preserved under set 
forcing, since any amount of collapse will still leave ordinal-many
