Line 829:
Then, gather rows where the first entry is the same. Keep the ones with at least two such entries (sorted by ascending order of sum).
Then, place an counting index (starting from 1) in front of each row, so the columns are now: '''counting index''', '''sum''', '''small cube''', '''large cube'''.
Note that the cube root of the 25th entry is slightly smaller than 74, so testing against the first 100 cubes is more than sufficient.
