....into a position in which they have no legal move. A strategy which accomplishes this has essentially the same structure as a proof of wellfoundedness. The idea of developing an arithmetic of competitive advantage for positions in terminating games has been extensively pursued by Conway and others [15], 41] 16] Conway did not however consider the metamathematical question of how competitive strength is limited by the programming system in which the strategies are written, which seems to be a question more in the province of proof theory. If proofs are programs, it does not follow that ....

....therefore has the desired involution. We do this by showing that ffl 00 : M M 00 g = fid M g in the structure group S(M 00 ) and hence fl 00 is h cobordant to the identity. The result then follows by the h cobordism theorem. Since the action of Ln 1 (Z[e] on S(M 00 ) is trivial [5, 36] this reduces to checking whether or not (fl) 2 Imfp : M 00 =Z 2 ; F=C] M 00 ; F=C]g.
