Are any non-trivial properties known about the constant 0.2357111317192329... that is obtained by catenating the digits of sequence of prime numbers in base 10 or in other bases, especially whether it is normal?



Prime analogue of Champernowne's constant
In base 10 this is called the *[Copeland–Erdős constant](https://en.wikipedia.org/wiki/Copeland%E2%80%93Erd%C5%91s_constant);* it is normal. See [this article](https://projecteuclid.org/euclid.bams/1183509721).
