In this post I look at numbers made from numbers.
The Copeland–Erdős constant is made by sticking together all the prime numbers into a number 2 then 3 then 5 then 7 then 11 etc.. 0.235711131719232931374143 A033308. One of these turtle logo pictures made from this number has a very odd pattern. With 1.5 million digits from prime numbers this pattern is made. The Copeland–Erdős constant is normal so I would expect the loop to eventually come back around.
