For a complete nonempty feasible-set family on ordered ground0..n-1,n0..4, validate Bouchet symmetric exchange: for every feasibleX,Y andu inX symmetric_differenceY, at least onev inthat difference (v=u allowed) makes X symmetric_difference{u,v} feasible. Ifv=u,{u,v} is SINGLETON: toggle once, do not cancel two XOR operations. No binary/normal/even assumption; ordinary matroids included as constant feasible-cardinality cases.
