Definition
The ordinary complex irreducible representation labeled 2 of D₈, specified by its character on the named conjugacy classes. Faithful real-type geometric doublet
Definition sourcesRepresentation identity
Reference properties
Character and identity
This is an abstract ordinary complex representation. Its character, rather than its dimension alone, fixes its identity within the specified group and class convention. Columns are 1, r², {r,r³}, {s,r²s}, {rs,r³s}. The character a is the determinant of the geometric doublet. [sources]
Tensor operations and physical use
Use the linked character workbench to count internal singlets and decompose tensor, symmetric, or exterior powers. Field statistics apply to the full label space, including Lorentz and species labels when present. A character decomposition does not specify normalized invariant tensors or Clebsch–Gordan coefficients. [sources]
Conventions and realization
The coefficient field is complex; real describes the Frobenius–Schur type of this complex irrep. Labels refer to the table published here, not an upstream row number. No matrix basis is selected. Convention profile: finite-ordinary-complex-v1. [sources]
