Left: a system of three coupled cells with two cell types (indicated by the circle and square) coupled in a way that there is no permutation symmetry but there is an invariant subspace corresponding to cells 1 and 2 being synchronised. The different line styles show coupling types that can potentially be permuted (after Fig. 3 in [135]). Middle: the quotient two-cell network corresponding to cells 1 and 2 being synchronised. Right: the same network structure shown using the notation of [137]
