As you know, 1 appears infinitely often in Pascal's triangle, while 2
appears just once. Each odd prime appears just twice.
But what about composite numbers? Does every composite number appear more
often than any of its nontrivial divisors? This would seem to be true for
even numbers greater than 2. At least it seems like powers of odd primes
appear only twice each.
The sequence I'm looking for seems to be A235868. Any thoughts?
