Prouhet-Tarry-Escott problem
From Wikipedia, the free encyclopedia
In mathematics, the Prouhet-Tarry-Escott problem asks for two distinct sets of m integers each, A and B, such that:
for each integer k from 1 to n.
For example, for m = 4 and n = 3, a solution is the two sets {492, 276, 618, 834} and {294, 438, 816, 672}, because:
- 4921 + 2761 + 6181 + 8341 = 2941 + 4381 + 8161 + 6721
- 4922 + 2762 + 6182 + 8342 = 2942 + 4382 + 8162 + 6722
- 4923 + 2763 + 6183 + 8343 = 2943 + 4383 + 8163 + 6723.
This problem was named after Prouhet, who studied it in early 1850s, and Tarry and Escott, who studied it in early 1910s.
