  * Creates a LOR mesh and finite element space
  * Assembles a LOR version of the bilinear form `a`
  * Creates a preconditioner of type `<T>` using the LOR-assembled version
  -* Creates a DOF permutation (if requires) to transition between the LOR and high-order DOF numbering
  +* Creates a DOF permutation (if required) to transition between the LOR and high-order DOF numbering
