    Maybe you can then explain to us what "nearby" means? Maybe show a concrete example and explain why one set is "nearby" and another, very similar set is not "nearby"?

    Just telling us "word puzzle" does not help. There are many types of word puzzles and your numbers don't explain at all how they relate to word puzzles.

      nearby mean the the next search character or number is the

      neighbour of my current position of "character or number"

      example number 2 neighbour number = 1,3,5,6,7

      number 7 neighbour number = 2,3,4,6,8,10,11,12

      number 12 neighbour number = 7,8,11,3,16

      and 16 inside the 12 neighbour's numbers so "2,7,12,16" consider related each others so should return "true".

        So, it seems to be a graphical neighborhood, if I understand correctly. For example, in this matrix: 
        ( [ x, x, x, x, x],
  [ x, y, y, y, x],
  [ x, y, z, y, x],
  [ x, y, y, y, x],
  [ x, x, x, x, x],
)

        the "y" elements are all neighbors of "z", but the "x" elements are not. Is my understanding correct?

        But I still don't see why [2, 4, 7, 12] should pass successfully your test in your original data set: 

        ( [ 1,  2,  3,  4,],
  [ 5,  6,  7,  8,],
  [ 9, 10, 11, 12,],
  [13, 14,  3, 16,],
  [ 2, 18, 19, 20,] )

        2 and 4 are not neighbors.

        Or did I miss something?
