It is very probable that the answering entity was a GMP -- but knock yourself out, if you want to be really sure it's a non-buggy GMP too.
But what I want to know is why it is more probable that the entity is GMP if the answer if ({32,1,1}) than if the answer is ({1,2,3}), i.e. why should we treat one incorrect answer as an error, but not another one? If all we're interrested in is that we get an answer, and don't care if it is correct or not, we should accept any answer (within the range of the function).
