      Following are the ratios of primes to total

      for Extended Ulam Spiral 107:

      30 .8

      40 .78

      50 .72

      60 .67

      70 .63

      80 .65

      90 .63

      100 .64

      110 .63

      Does this remain above 50% ?

      I would call {n =1..., 4n^2-10n+107} a dense set of primes?
