org.apache.commons.math3.random.MersenneTwister.nextLong()
Returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence. All 2⁶⁴ possible {@code long} valuesshould be produced with (approximately) equal probability. @return the next pseudorandom, uniformly distributed longvalue from this random number generator's sequence
