The Look and Say Sequence
Region:Taiwan, R.O.C.
City:Taipei, Other
Abstract:The Look and Say sequence was first introduced by John H. Conway. Starting with 1, every new row is produced by describing the previous row: 1 11 21 1211 111221 312211 …… To understand the sequence better, we worked out its exact formula using methods of group-dividing, repetition and cracks.
