%N Numbers n with the property that the relation 1-d!/((d-i)!d^i)>1/2 holds for integers d>2 between i-1 and n+i-1. The expression is the "birthday problem" probability out of d equally possible birthdays, while i is the smallest integer for which the relation holds given d, and n is the number of values of d for which the relation holds given i.
