## Statement

The rank-27 solder B from J3(Os) to the grade −2 shell preserves the full polarized cubic: Cshell(Bx,By,Bz) = Npol(x,y,z).

## Caution

Tensor equivalence does not make the unpointed shell select the transported unit or an intrinsic basepoint.

## Primary source

Appendix T, §15.1, The solder and transported pointing, PDF p.332: "The carrier arc begins with the exact rank-27 solder"
