Abstract
This note presents an example that disproves, for n=4, Weinbaum's conjecture, that if w is a cyclically reduced primitive word in F n such that all the generators x∈X appear in w then some cyclic permutation of w can be partitioned into n words generating F n :w≡uv, vu≡s 1 s 2...s n, <s 1, s 2,...s n >=F n .
