   Format: MarkdownItexI have added the picture of Dynkin diagrams that illustrates the exceptional iso $Spin(6) \simeq SU(4)$ ([here](https://ncatlab.org/nlab/show/Spin(6)#IsomorphismBetweenSpin6AndSU4)). Am adding this also at _[[SU(4)]]_ and at _[[A3]]_ <a href="https://ncatlab.org/nlab/revision/diff/Spin%286%29/9">diff</a>, <a href="https://ncatlab.org/nlab/revision/Spin%286%29/9">v9</a>, <a href="https://ncatlab.org/nlab/show/Spin%286%29">current</a>

   I have added the picture of Dynkin diagrams that illustrates the exceptional iso $Spin(6) \simeq SU(4)$ (here). Am adding this also at SU(4) and at A3

   Format: MarkdownItexI added another explanation of why Spin(6) is SU(4). I should do the same sort of thing for Spin(5) and Spin(4). <a href="https://ncatlab.org/nlab/revision/diff/Spin%286%29/11">diff</a>, <a href="https://ncatlab.org/nlab/revision/Spin%286%29/11">v11</a>, <a href="https://ncatlab.org/nlab/show/Spin%286%29">current</a>

   I added another explanation of why Spin(6) is SU(4).

   I should do the same sort of thing for Spin(5) and Spin(4).
