The task

Context: this statement belongs to family 322 of the release, *Tingley's sphere-isometry problem* (Functional analysis). The family as a whole: Resolves Tingley's problem: every surjective isometry between the unit spheres of nonzero real Banach spaces extends uniquely to a surjective real-linear isometry of the…
