Aug 15, 2023 at 14:39 comment added Abdelmalek Abdesselam There is a very rich theory of generalized ${}_pF_q$ hypergeometric series and identities they satisfy. In the terminating case (the parameters are such that the series is a finite sum) you get the combinatorial binomial sum identities. See en.wikipedia.org/wiki/Dixon%27s_identity and en.wikipedia.org/wiki/…
