Problem Statement

The Sports Associations in India (SAI) wants to choose 2 teams of 4 people each to send to Asian games. There are 13 people who want to be members of the teams. The SAI tries grouping them in various ways to see which athletes perform well together. Each grouping gets one test run on the test track and their time is recorded. Your task is to help the SAI choose two disjoint teams of 4 such that the sum of their practice times is minimal.

Input

There will be several input instances. The first line of each instance gives the total number of practice runs. This will be followed by n lines.
Each of those lines will contain 5 numbers: p1 p2 p3 p4 t t is the time taken (in milliseconds) by the team consisting of p1, p2, p3 and p4.

The time taken will not be more than 2 minutes.

The end of the input will be indicated by a line with n=0.

Output

Output the best total and the two teams that you choose.
If it is impossible to choose two disjoint teams from the test runs given, output -1.
