arXiv:2610.37885v1 Announce Type: new Abstract: We compute the $RO$-graded Tambara functor of $H\underline{\mathbb{Z}}$ for every finite cyclic group. We introduce a valuation language for homotopy groups: for prime-power cyclic group equivariant, classes are represented by compatible vertex arrays or by edge arrays. In these coordinates we compute products, restrictions, transfers, Weyl actions, and norms. Then we assemble the results into arbitrary finite cyclic group equivariant case. Besides the computation, we also develop the Tate compression theory, which is used in the computation. The Tate compression diagram cut an equivariant spectra into several layer, which the homotopy group can be describe directly by each layers. From it we also give a filtration for $\pi_\star(H\underline{\mathbb{Z}})$, compatible with products, restrictions, transfers, Weyl actions, and norms.
