I checked and CMWC Marsaglia is part of polymath
PMNumberGenerator allSubclasses an OrderedCollection(PMBernoulliGenerator PMBinomialGenerator PMConstantGenerator PMExponentialGenerator PMGaussianGenerator PMPoissonGenerator)
PMRandomGenerator allSubclasses an OrderedCollection(PMMarsagliaKissRandom PMLehmerRandomGenerator PMLinearCongruentialRandomGenerator PMMersenneTwisterRandomGenerator PMParkMillerMinimumRandomGenerator)
So we could pick one of them for Pharo. Stef
