Consecutive Numbers

[psofr]

I think that the most efficient way to present Consecutive Numbers Filter is by Pattern.
Eg, In lottery 6/49 :
Pattern: 2-2-1-1 means two consecutive pairs and two nonconsecutine numbers.
Pattern: 3-1-1-1 means one consecutive triplet and three nonconsecutine numbers.
Pattern: 3-2-1 means one consecutive triplet, one consecutive pair and one nonconsecutine number.
