::::: That seems overly wordy just to ask for the lowest positive sum that can't be expressed (within the rules). In particular, the requirement was expressly worded to find ''that'' sum. However, I will add an example (i.e.: such as 5074). -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 02:56, 1 January 2017 (UTC)

Note: If you allow/disallow negative first numbers you do get different results. If you allow negative first numbers, which you should according to the specification; then you get at least two targets with the same highest number of solutions: The positive and negative versions of the same target, only the positive one is between 0 to 123456789. The specification assumes there is only one positive target with the maximum number of solutions. It is worth looking for multiple targets with the same number of solutions, just in case there are more. This is especially true if you try the variants with different lists of digits. For example using the digits '987654321' and excluding a negative first number comes up with two distinct targets with the same maximum number of solutions, both of which happen to be positive. If you are playing with the asymetric version with out leading negative numbers of different lists of digits the sums with the highest number of solution may only be negative. In this case it is worth excluding the test to show only positive totals and put up with seeing duplicate +ve and -ve solutions.
