The following results summarize the relation between orientifold and D-brane, and SUSY charge $$\begin{array}{l||c|c|c|c|c|c}\text{orientifold} &\text{O4} & \text{O3} & \text{O2} &\text{O1} & \text{O0} \\ \text{D-brane involved} & \text{D2} &\text{D3} & \text{D4} &\text{D5} & \text{D6}\\ \text{SUSY on the D-brane} & \mathcal{N} =8 & \mathcal{N} = 4 & \mathcal{N} = 2 & \mathcal{N} =(1,1) & \mathcal{N} = 1 \\ \text{dimensons} & d=3 & d=4 & d=5 & d=6 & d=7 \end{array}$$ It looks that the spacetime dimensions correspond to $$d=3$$, $$d=4$$, $$d=5$$, $$d=6$$, and $$d=7$$.

Is it known how the SUSY charge $$\mathcal{N}$$ are related to the spacetime dimensions $$d$$?

But it seems that the relation does not directly relate to the familiar result between spacetime dimensions $$d$$ and SUSY charge $$\mathcal{N}$$? See https://physics.stackexchange.com/a/587879/42982
