===Sobol sequence===
{{Main article|Sobol sequence}}

The Antonov–Saleev variant of the Sobol’ sequence generates numbers between zero and one directly as binary fractions of length <math>w,</math> from a set of <math>w</math> special binary fractions, <math>V_i, i = 1, 2, \dots, w</math> called direction numbers. The bits of the [[Gray code]] of <math>i</math>, <math>G(i)</math>, are used to select direction numbers. To get the Sobol’ sequence value <math>s_i</math> take the [[exclusive or]] of the binary value of the Gray code of <math>i</math> with the appropriate direction number. The number of dimensions required affects the choice of <math>V_i</math>.
