You are quite right Bob. That was for the Triple.
For the Pairs Matched, if the Set of Numbers in Cells "D20:G20" was 2
19 30 instead of 2 19 24, then the Resulting Formula would have to
Return 1, being Numbers 2 & 19 because there was only 1 Pair that
Matched out of the 3 Pairs ( Originally Pair 1 = 2 19, Pair 2 = 2 24,
Pair 3 = 19 24 ) available from the Numbers in Cells "D20:G20" to the 6
Numbers in Cells "J16:O16".

Thanks in Advance.
All the Best.
