I just can't get this number out of my head. It's a number that has the decimal digits composed by all the prime numbers. 


The first digit is not important, it can be 0,2357... or 1,2357... 


Does any mathematician has studied this number? Is it transcendental? I guess I can prove it's not a normal number. Where can I find more about it?



Does the number 1,23571113... has been studied before?
The Copeland–Erdős constant is the concatenation of "0." with the base 10 representations of the prime numbers in order. Its value is approximately
0.235711131719232931374143… (sequence A033308 in the OEIS).


In base 10, the constant is a normal number, a fact proven by Arthur Herbert Copeland and Paul Erdős in 1946 (hence the name of the constant).
