### On the family of $D(4)$-triples {k-2, k+2, 4k^3-4k}

#### Abstract

In this paper we prove that if $k\geq3$ and $d$ are positive integers and the set $\{k-2,k+2,4k^3-4k,d\}$ has the property that the product of any two of its distinct elements increased by $4$ is a perfect square, then $d=4k$ or $d=4k^5-12k^3+8k$.
