    • There are many ways to construct the sequences (Formula presented) for the processors one through m. We used random numbers (Formula presented) generated by a single pseudorandom number generator to make nonoverlapping sequences (Formula presented) (Formula presented) and so forth.

    • Equation (2) is just one rational approach to consider the convergence of an exponent which characterizes power-law behavior. Another possibility given in Ref. 17 was found to yield consistent results in the asymptotic limit

    • To determine the exponent, there are various ways which yield essentially identical results. Estimation of the error bars is a different matter. Use of linear regression is one possibility, but this approach provides an error estimate that is unreasonably small. To obtain a more realistic estimate, we determined the error bars (given in Table I) on the basis of fluctuations in the running exponents

    • To determine (Formula presented), we calculated a given correlation function (Formula presented) of RANLUX4 ten times with (Formula presented) samples each up to (Formula presented). For each of these, we calculated (Formula presented) (Formula presented), with respect to (an independent calculation of) (Formula presented) of RANLUX4 with M samples. Then (Formula presented) is simply the mean of (Formula presented). The same procedure was carried out for all correlation functions (Formula presented) (Formula presented) and (Formula presented)
