Traves, William N. A remarkable integer identity. (English) Zbl 0804.05006 Bull. Inst. Comb. Appl. 10, 17-22 (1994). Summary: The integer identity \((1 + 2 + \cdots + n)^ 2 = 1^ 3 + 2^ 3 + \cdots + n^ 3\) is discussed. A number of proofs of the identity are given, the combinatorial proof leading to an elegant geometric proof.
