چكيده فارسي :
In this paper, we attempt to construct some 3-way $(v,k,2)$ Steiner trades, specially for $k=5$, by applying
some block designs, such as BIBDs, RBs, GDDs, and RGDDs, specially GDDs.\\
Also, we show the existence of a 3-way $(v,5,1)$ Steiner trade for each volume $s,\ s\geq 12$
except probably $s\in \{13,14,17,19,22,23,26,29\}$.
