In Preparation

The information below is preliminary and cannot be trusted! (v)

Sweeping clean a tree and ${\mathcal {A}}(\Gamma )\equiv {\mathcal {A}}(\uparrow _{b_{1}(\Gamma )})$ .

${\mathcal {A}}(\uparrow _{n})$ is a VS-algebra (see more at VS, TS and TG Algebras).
In the coordinates above, write the $TR\Phi B$ $TR\Phi B$ relations in various algebraic notations.
- R4: $(1230)^{\star }B\cdot (1213)^{\star }B\cdot (1023)^{\star }\Phi =(1123)^{\star }\Phi \cdot (1233)^{\star }B$ or $(B_{1a}B_{2a}\Phi _{1a};B_{1b}B_{2b};B_{1c}B_{2a}\Phi _{1b};B_{2c}\Phi _{1c})=(\Phi _{2a}B_{3a};\Phi _{2a}B_{3b};\Phi _{2b}B_{3c};\Phi _{2c}B_{3c})$ .
- R3: $(1230)^{\star }B\cdot (1213)^{\star }B\cdot (1023)^{\star }B=(1123)^{\star }B\cdot (1203)^{\star }B\cdot (1231)^{\star }B$ or $(B_{1a}B_{2a}B_{3a};B_{1b}B_{2b};B_{1c}B_{2a}B_{3b};B_{2c}B_{3c})=(B_{4a}B_{5a}B_{6a};B_{4a}B_{5b}B_{6b};B_{4b}B_{6c};B_{4c}B_{5c}B_{6a})$ .
- R2: $(123)^{\star }B^{\pm }\cdot (132)^{\star }B^{\mp }=1_{3}$ or $(B_{1a}^{\pm }B_{2a}^{\mp };B_{2b}^{\pm }B_{3c}^{\mp };B_{1c}^{\pm }B_{2b}^{\mp })=(1;1;1)$ .
- R1: $(B_{a}^{\pm };B_{b}^{\pm }B_{c}^{\pm })=(1;T^{\pm 2})$ .
- Symmetry of $\Phi$ and of $B^{\pm }$ .
- $u$ , $d$ and $\#$
- Idempotence for $T$ , $R$ , $\Phi$ and $B^{\pm }$ .
- $B^{\pm }$ in terms of $\Phi$ and $R$ and $R$ in terms of $T$ .

General Principle. Believe not, until you see a running program.
