We report on an ongoing study of the running coupling of SU(N) pure\nYang-Mills theory in the twisted gradient flow scheme (TGF). The study exploits\nthe idea that twisted boundary conditions reduce finite volume effects, leading\nto an effective size in the twisted plane that combines the number of colours\nand the torus period. We test this hypothesis by computing the TGF running\ncoupling and the SU(N) \Λ- parameter on asymmetric lattices of size\n(NL)2L2 for various gauge groups. Finite volume effects are monitored by\nanalyzing the coupling in different planes and by comparing results at\ndifferent number of colours.\n
