More on the Terwilliger algebra of Johnson schemes
Abstract
In [F. Levstein, C. Maldonado, The Terwilliger algebra of the Johnson schemes, Discrete Math. 307 (2007) 1621--1635], the Terwilliger algebra of the Johnson scheme J(n,d) was determined when n≥ 3d. In this paper, we determine the Terwilliger algebra T for the remaining case 2d≤ n<3d.
