      Since you guys seem to be looking at my question: as a measure of my
      respect for that, I shall give a little more.

      Each data set of 1's and 0's refers directly to a particular even
      number.

      e.g. for m = 68 we have.
      Dataset1

      3 11011011011011011011011011011011011011011011011011011011011011011

      5 11000110001100011000110001100011000110001100011000110001100011000

      7 10100001010000101000010100001010000101000010100001010000101000010


      For m = 66 we have.
      Dataset 2

      3 001001001001001001001001001001001001
      5 1001010010100101001010010100101001010
      7 0010001001000100100010010001001000100


      There can be more than one data set for each even number, e.g.

      for m = 68 we have.
      Dataset 3

      3 011011011011011011011011011011011011011011011011
      5 000110001100011000110001100011000110001100011000
      7 110000011000001100000110000011000001100000110000

      Each data set uses a specific RelativePrime term.
      For the first and second datasets it is 31 and for the third it is 29.

      The RelativePrime term has a maximum at around m/2 and a minimum at
      around m/4 or may be somewhat lower.

      I will find that throughout the dataset there are columns which
      contain all 0's.

      It is the columns immediately prior to those that I am interested in.

      I have called these columns A or n in previous posts (apologies).

      Let me call them A.

      For Dataset 1
      There are A's at columns 8, 17, 29, 32, 38, 47 etc as these are
      columns immediately prior, to columns containing all 0's,

      Can any of those A's fit the equation A = IntegerPart [105*n/31],
      where n is some whole number divisor, which is unknown?

      I have used RelativePrime = 31 in this case, as it is within the range
      for RelativePrime, for even number m = 68

      By observation, I can see that there is such an A for that specific
      Dataset 1, at column 47.

      At this column 47 = IntegerPart [105 * 14/31]

      For Dataset 2, I will use 31 again and for data set 3, I would use
      29 as the RelativePrime term.

      I need to find the general case, that given a dataset with the
      following limitations:

      1. Each row has a repeating pattern of 0's and 1's with period equal
      to the prime at the head of that row.

      2. There are no more than two 1's in each of those periods.

      And given the RelativePrime term is limited as above.
      And given that the PrimeProduct can only include the odd primes (thus
      it should be called the OddPrimeProduct); is calculated by taking the
      squart root of m and finding only the odd primes lower than it.

      Is it true that I will find an A in every dataset (given the dataset
      limitations) which will fit the formula

      A = IntegerPart[OddPrimeProduct/RelativePrime]
