Let X be a compact metric space and f:X→X be continuous. Let h⁎(f) be the supremum of sequence entropies over all subsequences of N. It is known that if X is a finite tree then h⁎(f)∈{∞,0,log2}. In this paper we focus on finite graph and obtain the same result. Namely, if X is a finite graph then h⁎(f)∈{0,log2,∞}.
