We investigate the homology representation of symmetric group on rank-selected subposets subword order. show that module for words bounded length, over an alphabet size $n,$ decomposes into a sum tensor powers $S_n$-irreducible $S_{(n-1,1)}$ indexed by partition $(n-1,1),$ recovering, as special case, theorem Bj\"orner and Stanley length at most $k.$ For arbitrary ranks we is integer combinatio...
