comment CompiledFunctionCall vs. LibraryFunction
@MariusLadegårdMeyer, in your question you are defining compBinomial to take real arguments but when you call it from within compsum you pass integer arguments. I think this type inconsistency is why the library function is not used.

comment Why does partitioning increase Dot execution speed?
I think with symbolic matrices you are just seeing an exponential increase in complexity with the number of matrices in the dot product - the timing is about the same for partitions of n and 24/n. The optimum partition size is probably around Sqrt[n].

comment Does Mathematica store hidden information for matrix objects?
A simple workaround is to create a new expression, e.g. AntihermitianMatrixQ[2 M / 2] or AntihermitianMatrixQ[0.0 + M]

comment Divide each element of a list of 500 matrices by another matrix
You have misremembered - automatic Listable threading works on the outermost dimension. In your example both lists are length 3 so it threads in all Mathematica versions.

comment Divide each element of a list of 500 matrices by another matrix
As kguler commented, why not just use M/div ?
