Abstract: Motivated by the recent calculation of the SL $$(K+3,\mathbb {C})$$ ( K + 3 , C ) symmetry of n-point Lauricella string scattering amplitudes (SSA) of open bosonic string theory, we calculate ratios of the solvable infinite linear relations of arbitrary n-point hard SSA (HSSA). We discover a general stringy scaling behavior for all n-point HSSA to all string loop orders. For the special case of $$n=4$$ n = 4 , the stringy scaling behavior reduces to the infinite linear relations and constant ratios among HSSA conjectured by Gross (Phys Rev Lett 60:1229, 1988) and later corrected and calculated by the method of decoupling of zero-norm states (Chan et al. in Phys Rev Lett 96(17): 171601, 2006).
