On a group of normalized solutions of the higher-dimensional Prouhet--Tarry--Escott problem
Munenori Inagaki, Hideki Matsumura, Masanori Sawa +1
We elucidate, for the first time, a novel group-theoretic structure that arises from certain solutions of the -dimensional Prouhet--Tarry--Escott problem of degree and size…
