Analogous to the work of Xiong on the largest size of an (s, s + 1, …, s + k)-core partition, we evaluate the largest size of a self-conjugate (s, s + 1, …, s + k)-core partition for given positive integers s and k. This generalizes the result on the largest size of a self-conjugate (s, s + 1, …, s + k)-core partition, which is obtained by Baek, Nam, and Yu by employing Johnson’s bijection.</abstract><keywords/></article-meta></front><body/><back><ref-list><ref id="B1" content-type="article"><label>1</label><element-citation publication-type="journal"><p>Anderson J, 2002, Partitions Which Are Simultaneously t1- and t2-Core.
