## Statement

Inside V56, the so(5,5) physical-vector ten is isomorphic to the selector ten as a Kdyn module, with Casimir 1/6.

## Caution

This module isomorphism does not identify either ten with the distinct boundary-adjoint module.

## Primary source

Appendix X, Carrier fence beside clause 27: three tens, PDF p.371: "The physical/vector ten (the so(5, 5) vector inside V56 , Kdyn -Casimir 1/6) is isomorphic to the selector ten (two-host certified; kernel s1067)"
