S = $ s\exp{1} <\math> IF S is discrete but infinite, S = {,,,....} ex. S = {1,2,3,4,...} S = {sin(2*440t),sin(2*880t),sin(2*1320t),...} Observe S = is not routable; S = [0,1] is not routable S = {sin(2*f*t)} = {sin(2*f*t)|0} is all integers -to  Is routable? yes. ={0,1,-1,2,-2,3,-3, }as opposed to  = {0,3,e,,-1,1.14,, } Many different ways to write a set [0,1] = {xsuch that(s. t.) 0x 1} ={real positive numbers no greater than 1 as well as 0} $
