@MikeMiller Right, I'm just confused by the following: A framing of such a path should be a map $I\to O$ right? But we want this to land in $SO$ at time 1 and in $-SO$ at time 0 right? How's that possible?
@MikeMiller So the $0$-manifold $\{p\}$ has exactly two framings. Can you tell me why $\{p\} \sqcup \{q\}$ where the two points have distinct framings is zero is $\Omega_0^{fr}$ ?
