摘要：
We prove two cases of a strong version of Dejean's conjecture involving extremal letter frequencies. The results are that there exist an infinite (5/4(+))-free word over a 5 letter alphabet with letter frequency (1)(6) and an infinite ((6)(+)(5))-free word over a 6 letter alphabet with letter frequency (1)(5).
