2 There is a complete order-preserving functional mapping from the particles in 
the {particles} of R to the particles in the {particles} of B such that all of 
the following must be true: ... 

[Definition:] A complete functional mapping is order-preserving if each 
particle r in the domain R maps to a particle b in the range B which follows 
(not necessarily immediately) the particle in the range B mapped to by the 
predecessor of r, if any, where "predecessor" and "follows" are defined with 
respect to the order of the lists which constitute R and B. "
