comment $S_k(x+y)-S_k(x)-S_k(y)$ where $S_k$ is symmetric polynomial
But yeah, similarly to what Alex said above it may be useful to think about the cohomology of $BU$ or something.

This looks like the image of $S_k$ under the coboundary operator on Hochschild 2-cochains of the additive group of $\mathbb{Z}$, I think. Hmmmmm... but I don't know of a closed form.

comment Difference between coherent nerve of simplical model category and simplicial category
@AaronMazel-Gee thanks! But what if we only look at the underlying simplicial category of a simplicial model category? How does the coherent nerve of this category relate to the other constructions?
