Congruences modulo 5 for the number of spin characters of the double covers of the symmetric and alternating groups
Ernest X. W. Xia · Acta Arithmetica · 2019
Recently, Nath and Sellers established a characterization of the number of spin characters of $ \hat{S}_n $ and $ \hat{A}_n $ modulo 2 and 3, where $ \hat{S}_n $ and $ \hat{A}_n $ are the double covering groups of the symmetric group $S_n$ and the alterna
