  In this paper we extend the Robinson-Schensted-Knuth (RSK) superinsertion
algorithm to hook-multipartitions and derive the super Frobenius formula for
the characters of cyclotomic Hecke algebras (Linear and Multilinear Algebra,
DOI: 10.1080/03081087.2019.1663140) via the RSK superinsertion algorithm. In
particular, we obtain a new proof of Mitsuhashi's super Frobenius formula for
the characters of Iwahori-Hecke algebras.
