# Advanced number generator - Consec, Even/Odd and Space ## 5. Consec., Even/Odd and Space filters

### Consecutive numbers

This filtering section makes it possible to define how many consecutive numbers each of the generated results should or should not contain.
For instance, if you would like to generate only lottery results that have at least one set of 2 consecutive numbers but not more than two, you would set, next to "2 consec.", the Min. drop down menu to 1 and the Max. drop down menu to 2.
To restrict all consecutives in the generated lotto results set all (Min AND Max) consec drop down menus to 0 (zero).

### Even/Odd numbers

This section of the filters also allows you to define how many evens and how many odds each generated combination should contain.
For example, if you set the Min.E and the Min.O fields to 2, and Max.E, Max.O to their highest possible values, each generated combination will have at least 2 even numbers and at least 2 odd numbers.

Tip: In order to generate lotto results that have only one even or only one odd, number generator needs to be used in two different sessions. During the first session the Min.E/Max.E would be set to 1 and the Min.O would have to be set to 2 while the Max.O would be set to its highest value.
In the second session the Min.E would be set to 2, the Max.E would be set to its highest value and the Min.O/Max.O would be set to 1.

### Space between numbers

In the previously discussed number generator filtering section, we have been looking at the Smallest difference and the Greatest difference between two adjacent numbers.

Here, we can take that one step further and define the distances (differences), individually, between any two adjacent numbers.

And... to take it even further than that, the number generator gives you the possibility to even set how many of the spaces can be the same.

Example: we take numbers 05-15-20-25-27.
The spaces between these numbers are 5, 5, 5 and 2, right?

By setting the "Space repeat" filter to 1 and 2, the number generator would eliminate the above set of numbers. Reason for that being the fact that it has 3 repeating spaces (5, 5 and 5) and another space, 2, which appears only once.

In order to have the above set of numbers returned by the generator, this filter would have to be set to Min = 1 and Max = 3 (or higher), just as it is in the screen-shot below. It needs to be pointed out that, less numbers drawn from a larger pool have a lower space repeat rate while more numbers, especially if drawn from a smaller pool, have a higher space repeat rate. Take a look at the space repeat rate for the following 3 lottery games.

## Space repeat rates

See? The US Powerball has mostly a space repeat rate of 1/1, meaning that the spaces between two adjacent numbers are different.
Euromillions is just a little bit off, spaces being repeated twice sometimes but in the Australia Set For life, an 8/37 lottery system, the spaces are repeated twice most of the time. Even three times here and there.

The space repeat rate for every lottery we analyze is in the "Spaces (Dist.)" column in the Lottery Matrix table.
