Eliminating records with sequences of numbers

[spfleck]

I have a large database with over 6 million records. Each record has only 7 fields, all numeric.

I would like to eliminate records that contain fields where the numbers are sequential in at least 4 fields.
Here's an example:

1,2,3,4,11,22,43 should be eliminated
1,22,23,24,25,37,132 should be eliminated

Can anyone think of an elegant method without manually searching and deleting?

Thanks!

The only ways that come to mind involve a function that would test the values and either return a value or actually delete the record. It would use a counter variable that would either increment or reset depending on whether the values being tested were sequential.
