Abstract
We compute the pages of the momentum-space and real-space Atiyah-Hirzebruch spectral sequence (AHSS) for topological crystalline insulators and superconductors up to three spatial dimensions, using cell decompositions such that any group element that fixes a cell setwise also fixes it pointwise. We provide a detailed description of the implementation for computing the pages of AHSS. Under a physically reasonable assumption, we enumerate all possible -groups that are compatible with the pages for both momentum and real-space AHSS. As a result, we determined the -groups for approximately 59% of symmetry settings in three spatial dimensions.
