 comment The polynomial where only the terms in the multinomial series where each variable's exponent is $>0$ are kept?
@anon Has such a function being studied before? I'm looking for some asymptotic results on this function.

@BrianM.Scott I think you guys didn't notice that $i_1>0,i_2>0,...,i_k>0 $

I'm actually thinking more about results more exact than the Lander-Waterman model (when the sequence being sequenced is shorter)
