   Format: MarkdownItexI have added mentioning of the model of EM-spaces $K(A,n)$ as the "reduced A-linearization of the $n$-sphere" $A[S^n]_\ast$ (for countable $A$, at least), [here](https://ncatlab.org/nlab/show/Eilenberg-Mac+Lane+space#ReducedALinearizationOfnSphereIsEMSpace). (That's the model of EM-spaces which lends itself to the definition of the EM-spectrum as an orthogonal spectrum)
