| Mar 6, 2014 at 15:06 | comment | added | Geordie Williamson | It is a result of Billey and Warrington that "321 hexagon avoiding" permutations in the symmetric group admit small resolutions. See: Billey and Warrington, Kazhdan-Lusztig Polynomials for 321-hexagon-avoiding permutations, J. of Algebraic Combinatorics, v. 13 (2001), no. 2, 111--136. | |

For example, beyond Zelevinsky's 1983 paper, MathSciNet turns up quickly five others which may be relevant to your question: B.F.Jones (2010), N. Perrin (2007), J. van Hamel (2003), P.Sankaran and P. Parameswaran (1994, 1995). At least some of these must be on arXiv. There has certainly been some related study though it might not fit your question exactly. | |
