For integers n,k ≥ 1, let Sk(n) denote the power sum 1k +2k + ⋯ + nk. In this note, we first recall the minimal recurrence relation connecting Sk(n) and Sk-1(n) established by Abramovich (1973). We then discuss an old algorithm to determine the coefficients of the power sum polynomial Sk(n) in terms of the coefficients of Sk-1(n) (see, e.g., Bloom (1993) and Owens (1992)). Moreover, we bring to light an explicit relationship between Sk(n) and Sk+1(n) put forward by Budin and Cantor (1972). We conclude that these procedures (including the integration formula expressing Sk(n) in terms of Sk-1(n)) all constitute equivalent methods to determine Sk(n) starting from Sk-1(n). In addition, as a by-product, we provide a determinantal formula for the Bernoulli numbers involving the binomial coefficients.
