There are two combinatorial ways of parameterizing the J b (F)-orbits of the irreducible components of affine Deligne-Lusztig varieties for GL n and superbasic b. One way is to use the extended semi-modules introduced by Viehmann. The other way is to use the crystal bases introduced by Kashiwara and Lusztig. In this paper, we give an explicit correspondence between them using the crystal structure.
