  We aim to investigate the four types of variant Euler harmonic sums. Also, as
corollaries, we provide particular examples of our core findings, some of whose
further instances are evaluated in terms of basic and well-known functions as
well as certain mathematical constants. We explore relevant linkages between
our results and those of other previously established studies. An examination
of a specific case of one result shows a relationship to series involving zeta
functions, which is also a popular area of research.
