      Record runs above 36:
      40 with no 9: 62024761 to 62025377
      43 with no 3: 133125211 to 133126009
      48 with no 1: 149054309 to 149055259
      51 with no 1: 1206644317 to 1206645493
      53 with no 9: 1770847261 to 1770848447
      54 with no 3: 2343368669 to 2343370021
      57 with no 3: 2462372461 to 2462373707
      61 with no 9: 76047287171 to 76047288677
      62 with no 7: 86722358543 to 86722360553

      It seems highly likely there can be arbitrarily many.
