Fermionic

enum class syten::Fermionic : char

strong

Speficiation when a particular label is fermionic.

This is only a rule under which condition an IREP with a given label is fermionic, i.e., here we only specify if a symmetry is never fermionic (such as for bosons), fermionic if the associated label is odd (particle number) or fermionic if the associated label is a half-integer (Sz).
