Hello there,
I'm trying to see if I could use STIR to reconstruct image from the simulated data for a bit of custom design PET. It has two layers but they are not nicely stacked and not of the same…

Currently, it seems that symmetry breaking is rather ad-hoc. For example, even though n-queens and knights tour both involve a square matrix with rotational and reflective symmetry, based on the dihe…

Since this runs in the CI we need to be a little conservative on what we time, some ideas:
## Systems:
- Something with many k-points but low Ecut
- Something with many symmetries
- Something wi…

Besides the supersymmetric theories to be listed in other issues, there are also many others (actually some below are supersymmetric, I didn't filter them yet):
- free (what are dimensions of various …

To reduce the number of irreducible kpoints in crystals without inversion symmetry. See discussion at https://github.com/JuliaMolSim/DFTK.jl/issues/203. This is distinct from exploiting TRS to reduce …

Octahedral symmetry should support also o as well as oct
If o is introduced the protocol fails after a very long time. The best solution could be a enumerate param to select the symmetry

Hi,
it seems that the calculation of free energy could be improved. In particular, is not clear whether the symmetry number sigma is computed from the dynamical matrix or not. In any case the symmet…

by default it uses orthogopt(). this should be changed.

I do not exactly understand what this title means (or meant).
The message should be: any group is a group of permutations.
Re first occurrence of "symmetry": this is rather an element of a group, …

Following a request from Jonathan Thornburg we include the following indices convention which is standard but up to now not implemented.
`X_{ab} := Rc{}_a{}d{}_b \bar{h}_{cd}`
