Description: 0 is not a prime number. Already Definition df-prm 16612 excludes 0 from being prime (ℙ = {𝑝 ∈ ℕ ∣ ...), but even if 𝑝 ∈ ℕ0 was allowed, the condition {𝑛 ∈ ℕ ∣ 𝑛 ∥ 𝑝} ≈ 2o would not hold for 𝑝 = 0, because {𝑛 ∈ ℕ ∣ 𝑛 ∥ 0} = ℕ, see dvds0 16218, and ¬ ℕ ≈ 2o (there are more than 2 positive integers).
