symmetric monoidal (∞,1)-category of spectra
Given a cardinal number , an n-ary operation on a set is a function
from the th cartesian power of to itself, where [n] is a set with elements. The arity of the operation is .
More generally, an n-ary operation in a multicategory is just a multimorphism.
Every set with an -ary operation comes with an endomorphism called the -th power operation
where is the diagonal morphism.
