The slice filtration focuses on producing certain irreducible spectra, called slices, from a genuine \(G\)-spectrum \(X\) over a finite group \(G\). We have a complete characterization of all 1-, 0-, and (-1)-slices for any such \(G\). We will characterize 2-slices over \(C_2\) and expand this characterization to \(K_4 = C_2 \times C_2\).
