Abstract: This paper reports on new results for the equation

\begin{equation*}\sum _{i=1}^{m}  a_{i}^{k}=\sum _{j=1}^{n} b_{j}^{k},\end{equation*}

i.e., equal sums of like powers. Since the 1967 Lander, Parkin and Selfridge survey paper [4], few other numeric results have been published (see Elkies [6] and Ekl [3]). The present paper reports on several new smallest primitive solutions. Further, search limits have been extended in many cases, and tables of solutions are presented. Additionally, new solutions to the same class of problems in distinct integers have been discovered.
