;Interesting details
===Levels===
For resolutions in <math>[N_{min}, N_{max}]</math>.
* Resolution at level l: <math>N_{l} = \lfloor N_{min} * b^{l} \rfloor</math>
* <math>b = \exp \left( \frac{\log N_{max} - \log N_{min} }{L-1} \right)</math>
 
===Hashing Function===
* Hash collisions are ignored.
* Hash collisions are ignored.
* The hash function used is: <math>h(\mathbf{x}) = \left( \oplus_{i=1}^{d} x_i \pi_i \right) \mod T</math>
* The hash function used is: <math>h(\mathbf{x}) = \left( \oplus_{i=1}^{d} x_i \pi_i \right) \mod T</math>
