Formal target: Corpus.Erdos11.erdos_11
Is every odd $n > 1$ the sum of a squarefree number and a power of 2?
Exact formal statement
∀ (n : Nat),
Odd.{0} n →
LT.lt.{0} 1 n →
Exists.{1} fun k =>
Exists.{1} fun l => And (Squarefree.{0} k) (Eq.{1} n (HAdd.hAdd.{0, 0, 0} k (HPow.hPow.{0, 0, 0} 2 l)))This target is a formal statement, not a proof of the problem.
