Or, denominator of 2^n/n! differs from denominator of sum(k=1,n,C(n-1,k-1)*2^k/k!).

We conjecture that the sequence is infinite, the sequence and its complement (cases where the two values are equal) equipartition N and the difference between consecutive members of this sequence never exceeds c=7.
