In the DHKE protocol using the prime p=467 and the primitive element alpha=2, the private key, say a, should be randomly selected from the set {2,...,p-2}. If a=1 what would be the corresponding public key?

In the DHKE protocol using the prime p=467 and the primitive element alpha=2, the private key, say a, should be randomly selected from the set {2,,p2}. If a=1 what would be the corresponding public key? A= Would you recommend using this value for a ? (Y/N) if a=466, what would be the corresponding public key? A= Would you recommend using this value for a? (Y/N)
