Published 16 Sep 2019 in math.AT and math.GT | (1909.07047v1)

Abstract: This small note, without claim of originality, constructs the projective plane over the octonionic numbers and recalls how this can be used to rule out the existence of higher-dimensional real division algebras, using Adams' solution of the Hopf invariant $1$ problem.
