[seqfan] Re: Excess permutation left moves over right moves

[Ron Hardin]

Also, though I am not yet doing it, you can add an a(0) term to the recurrences 
by subtracting one
from the respective "equal left and right" base series, as the lead shifting 
column entry.

Which might be glossed as "all permutations except the identity permutation" 
throughout.
