+"Ho ho ho", Santa muses to himself. "I forgot the trunk".
+
+Balance the sleigh again, but this time, separate the packages into **four groups** instead of three. The other 
+constraints still apply.
+
+Given the example packages above, this would be some of the new unique first groups, their quantum entanglements, and 
+one way to divide the remaining packages:
+```
+11 4    (QE=44); 10 5;   9 3 2 1; 8 7
+10 5    (QE=50); 11 4;   9 3 2 1; 8 7
+9 5 1   (QE=45); 11 4;   10 3 2;  8 7
+9 4 2   (QE=72); 11 3 1; 10 5;    8 7
+9 3 2 1 (QE=54); 11 4;   10 5;    8 7
+8 7     (QE=56); 11 4;   10 5;    9 3 2 1
+```
+Of these, there are three arrangements that put the minimum (two) number of packages in the first group: `11 4`, `10 5`, 
+and `8 7`. Of these, `11 4` has the lowest quantum entanglement, and so it is selected.

+Now, what is the **quantum entanglement** of the first group of packages in the ideal configuration?
