	    There is no order of the children.
	   
No, the children of a tree represented by a Prolog term
cannot help but be in *some* order.  If the problem does not
specify a natural order, is there something about the processing
that suggests a natural order (perhaps ascending or descending
order of weight?), or would any arbitrary order suffice?
