Dennis White reported the following error in "Subgroup lattices and
symmetric functions": Proposition 2.4.36 is false. In the computation
of charge, corresponding subwords of Knuth equivalent words need
not be Knuth equivalent. For example: w=24213431 has subwords
w1=2431 and w2=2413; v=42213431 has subwords v1=2431 and
v2=4213; w and v are Knuth equivalent, but w2 and v2 are not.
Corollary 2.4.38 is true.
