Abstract
In this paper, analytically and combinatorially, we reprove that the number of inversion sequences that avoid {100, 101, 201, 210} (respec-tively, {100, 110, 201, 210}) is given by the large Schröder number, as shown by Martinez and Savage. Moreover, we show that the number of inversion sequences that avoid {101, 110, 201, 210} is also given by the large Schröder number.
