The Morris sequence is built by taking the verbal description of a number sequence and converting every number or named numeral to a number in order. Typically, starting with the integer 1, the spoken description is "One 1," so the next sequence is c(1,1). Read that out loud as "Two ones", so the next sequence is c(2,1) and so on.
