Number with 4 digits ,you have to find pairs,A formula that suits all 4 different situations

for example

The number ,1234 there are 6 pairs ,{12;13;14;23;24;34}

The number ,5668 there are 4 pairs ,{56;58;66;68}

The number ,5777 there are 2 pairs,{57;77}

The number ,7777 there are 1 pair, {77}

You can start the solution, from first row, or second row,

Write a formula that displays the nth largest unique number from the Data column for items in the Item column that match the currently selected Lookup Item.
