Key variety construction of Sarkisov links for prime $\mathbb{Q}$-Fano threefolds of codimension four associated to Type ${\rm II}_{2}$ projections
Explicit Sarkisov links are constructed for seven families of codimension-four prime Q-Fano threefolds, terminating in del Pezzo surface fibrations of degree one or (2,1)-type divisorial contractions to low-codimension weighted complete intersections.
