COMMENTS
This sequence is the same as A033149, but uses correct [a_0; a_1, a_2, ...] indexing of continued fraction terms.
The smallest numbers not occurring in the first 4,851,382,841 terms of the c.f. are 27943, 33436, 33978, 34017, ... - Eric W. Weisstein, Jul 22 2013

EXAMPLE
The c.f. for gamma is A002852 = [0; 1, 1, 2, 1, 2, 1, 4, 3, 13, ...].
1 occurs first at term a_1
2 occurs first at term a_3.
3 occurs first at term a_8.
4 occurs first at term a_7.
