How it is written

  • (501a xxx 501n)
  • (501a xxx 50 In) with (I)

501a xxx 501n is Meyer's shorthand for a run of the same thing: 501a is the first, 501n the last, and the x's stand for however many lie between. Every stage of the run is this one numeral. A pair before the letters, 583/602a, is a run of two things that go together, one of each per stage.
