In this paper we will show that finitely generated torsion-free 2-stepnilpotent groups of Hirsch length at most 6 do not have the$R_{\infty}$-property, while there are examples of such groups of Hirsch length7 that do have the $R_{\infty}$-property.

$R_{\infty}$-property for finitely generated torsion-free 2-step nilpotent groups of small Hirsch length
