//metacat example:
//a b c => a b d
//w x y => ?
//correct: w x z

//making them similar arcording to relative alphabet position
<a <-> w>.
<b <-> x>.
<c <-> y>.
<d <-> z>.
//declaring two of them as similar
<(*,a,b,c) <-> (*,a,b,d)>.
//but if this is similar, to what is w,x,y similar then?
<(*,w,x,y) <-> ?what>?

OUT: <(*,w,x,y) <-> (*,w,x,z)>. %1.00;0.39%
