Entropy = 5.513632 bits per byte.

Optimum compression would reduce the size
of this 4248 byte file by 31 percent.

Chi square distribution for 4248 samples is 30440.12, and randomly
would exceed this value less than 0.01 percent of the times.

Arithmetic mean value of data bytes is 85.0918 (127.5 = random).
Monte Carlo value for Pi is 4.000000000 (error 27.32 percent).
Serial correlation coefficient is 0.283722 (totally uncorrelated = 0.0).
