I am not making any claims about digits of pi, however, one can take an arbitrary bit string (eg: an image of Nelson Mandela's representation), treat it as a number and extend its digits to generate a prime number or a perfect power. See: https://www.ias.ac.in/article/fulltext/reso/015/10/0941-0947 https://www.ias.ac.in/article/fulltext/reso/015/10/0941-0947 So, one could in theory create a list of primes (or perfect powers) populated them with hidden content using the aforesaid method and claim they are only a list of primes (or perfect powers).
