theorem Erdos366.erdos_366 :
(∃ (n : ), Nat.Full 2 n Nat.Full 3 (n + 1)) sorry

Are there any $2$-full $n$ such that $n+1$ is $3$-full?

Note that $8$ is $3$-full and $9$ is 2-full.

Are there infinitely many 3-full $n$ such that $n+1$ is 2-full?

theorem Erdos366.erdos_366.variant.weaker :
(∃ (n : ), Nat.Full 3 n Nat.Full 3 (n + 1)) sorry

Are there any consecutive pairs of $3$-full integers?
