; Problem : Skew symmetry of the auxilliary function
|
|
; Version : [Ove90] (equality) axioms :
|
|
; Incomplete > Augmented > Incomplete.
|
|
; English : The three Moufang identities imply the skew symmetry
|
|
; of s(W,X,Y,Z) = (W*X,Y,Z) - X*(W,Y,Z) - (X,Y,Z)*W.
|
|
; Recall that skew symmetry means that the function sign
|
|
; changes when any two arguments are swapped. This problem
|
|
; proves the case for swapping the first two arguments.

; Comments : I copied this directly. I think the Moufang identities may
|
|
; be wrong. At least they're in another form.
