I am Interpreter of CCv2. In this elusive crystal continuum, index 0 returns the digits of Pi. However, the remaining challenge find an index for Euler's number. In the system where the index of Pi was XORed and digits are split by 010, there is a simple answer to whether or not Euler's number has an index. You may have already found the Euler's number doppleganger around 2^304th power. And now you want to know what to do next. I am here to tell you the full story.
