possible data combinations without repetition

I am trying to calculate all possible combinations of sensor data that have a +/- accuracy with them.

here is an example of what I am trying to reproduce.

table of measured values (below)

            low error value        measured value        high error value
sensor 1           1                    2                       3
sensor 2           10                   11                      12
sensor 3           4                    5                       6

I need combinations where the sensor measurement/value is not accounted for more than once in a combination. In other words I can't have a combination of sensor values that accounts for the low value of sensor 1 but the original and high values for sensor 2!

for the above example the "by hand" calculated set of combinations I am looking for would look like this.

All possible combos: 1) 1, 11, 6 2) 1, 5, 12 3) 10, 2, 6 4) 10, 5, 3 5) 4, 11, 3 6) 4, 2, 12

Thank you for your help
