摘  要:：A regular (resp. singular) continuant is the denominator of the regular (resp. singular) continued fractions. C. A. Nicol posed the following problem: given any finite sequence of positive integers, find the permutations whose continuant attain the extremal values. The answers are known for the regular continued fraction expansion, as well as the minimal continuants in the singular expansions. While only partial results exist for the case of maximal singular continuants. We introduce the notation of harmonic sequences, and then elucidate the arrangements of the maximal singular continuants for the sequences consisting of three letters.
