In the nodal model, a loop is a circularly linked list formed from nodal associations. Since none of the nodes in a loop is a starting or finishing point, a loop can be referenced by any of its node-items. This means that a reference to a loop can also encapsulate the concept of an item of current focus, a concept used heavily by nodal reduction
Note that although one node can be the value of many associations at the same time, it can only occupy a single loop at any one time, because its position in a loop is determined by its PREV and NEXT associations.
