| Keywords | Weak factorization system; fibrantly generated; projectivity class; Vopěnka’s principle; accessible category |
| Description | We prove that, assuming Vopěnka’s principle, every small projectivity class in an accessible category is accessible. This conclusion is not provable in ZFC alone, and in fact carries large cardinal strength. |
