I have the following table in Mysql: Cod,D1,D2,D3,D4,D5,D6,D7,D8,D9,D10,D11,D12,D13,D14,D15 D1...D15 fields are filled with values between 1 and 25 in each record. There is no repetition of values within a record. How can I perform queries to find more frequent groups that repeat in the records? Example: identify how many times the group of values 1,5,10,15,20,25 appeared in the records. It would be possible to create a generic query to identify which groups had more frequency?
