I if understand well your example, you could try this workaround:
1) Create a Formula-Text column that combines A, B & C. Let's call it [A+B+C]. The formula can be something like: List(" ", [A], [B], [C])
2) Create a relation of this table to itself. Add these 2 matching conditions:
3) Create under this relation a summary column that counts the # of records. Let's call it [Count]. If the [A+B+C] value is duplicated in some of the records, the first one will have a value of 0, but the duplicates will have a value of 1, 2, 3, etc.
4) Create a view with a [Count]>0 filter to see only the duplicates.
