Well, that's your usual exit strategy. You could have just said you are out of your depth.
I have made no such claim.
Informally the claim is that Tree(3) is nether odd nor even.
Formally the claim is that there exists no proof for TREE(3) inhabits the Odd-type AND there exists no proof that TREE(3) inhabits the Even-type.
Maybe you don't understand the terminology?
In Classical Mathematics it doesn't. In constructive Mathematics it does.
You don't get to claim an object is either X or not-X without telling me which dusjunct holds - that's just re-stating Excluded Middle.
