COMMENTS

These numbers are known to occur at least six times in Pascal's triangle.

The next term is approximately 3.537 * 10^204 and is too large to include.

Equals binomial(A089508(n), A081016(n-1)) which is also binomial(A089508(n)+1, A081016(n-1)-1).

The numbers of digits in a(n), n>=1, are given in A100022.
