Comments

This is part 2 of a combined pseudorandom number generator proposed by Pierre L'Ecuyer. For more information, references and links see A096560. For the spectral properties see Table 1, line 21, on page 106 of Knuth's TAOCP Vol. 2.

This sequence has period 2^31 - 250. - Charles R Greathouse IV, Sep 10 2015
