comment How many possible permutations are possible if ranking n entities using the 'standard competition ranking' strategy?
I think your 12255 should be 12245.

It is true for all $2\times2$ matrices $A$ and $B$ over $\Bbb{C}$.

comment Type of isomorphism
There is always the natural map $$K\ \longrightarrow\ \operatorname{End}(M):\ x\ \longmapsto\ (m\ \longmapsto\ xm),$$ which is a morphism of $K$-modules, but this is rarely an isomorhism.
