Abstract

Let GG be a finite group, Ω(G)\Omega(G) be its Burnside ring, and Δ(G)\Delta(G) its augmentation ideal. Denote by Δn(G)\Delta^n(G) and Qn(G)Q_n(G) the nn-th power of Δ(G)\Delta(G) and the nn-th consecutive quotient group Δn(G)/Δn+1(G)\Delta^n(G)/\Delta^{n+1}(G), respectively. This paper provides an explicit Z\mathbb{Z}-basis for Δn(H)\Delta^n(\mathcal{H}) and determine the isomorphism class of Qn(H)Q_n(\mathcal{H}) for each positive integer nn, where H=g,hgpm=hp=1,h1gh=gpm1+1\mathcal{H}=\langle g,h |\, g^{p^m}=h^p=1, h^{-1}gh=g^{p^{m-1}+1}\rangle, pp is an odd prime.
