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)J(n,d) was determined when n3dn\geq 3d. In this paper, we determine the Terwilliger algebra T{\mathcal T} for the remaining case 2dn<3d2d\leq n<3d.
