%N List of distinct greatest common divisors of { k! and k! - (k-1)! + (k-2)! - ... + (-1)^k*0!, k = 0 .. n}.
%C Records in the sequence gcd(k!,A058006(k)). The record indices are products of primes from A064384. There are no further terms unless there are terms in A064384 larger than 463. - _Max Alekseyev_, Jul 06 2010
