Grushko's theorem [Mat. Sb. 8 (1940) 169–182] says that any generating tuple (g1, …, gm) of a free product H*K is Nielsen‐equivalent to a tuple (h1, …, hl, kl+1, …, km) with hi ∈ H and ki ∈ K for all i. The hi and ki are clearly not unique. In this paper we address the extent of this non‐uniqueness.
