Hi Marc,

The maximum amount in the debit column is 21,00,000. They are made up of 7 amounts of 3 lakh.
The maximum number of values in the credit side (the count) that net off for a single debit amount is 12.
Further apart from the values that knock off each other (equal and opposite individual numbers). The total combinations that knock off each other could be upto 45.

I hope this is what you were asking for. Does this help ? Please let me know.
