โฆ Synopsis
In this communication we shall prove a curious identity of sums of powers of the partial sum of binomial coefficients.
An identity
Theorem. C;=O (~~_o(~))3=n23"-1+23"-~2"(~).
Proof. Definef,=C;=, (Ci=O(k"))3. It is sufficient to show that Write A,=C:=,(,"). Then fn=C;=oA:.

We give a fairly direct proof of an identity involving powers of sums of binomial coefficients established recently by Neil J. Calkin, and present some associated formulae. I This research was carried out while the author was on leave from UNSW and visiting
coefficients.
A sequence b n is the binomial transform of the sequence a n if b n = n k=0 n k a k . We derive a general identity for such pairs of sequences. Various known identities are obtained as particular cases.
