 OFFSET 1,1 COMMENTS See the formula section for more data, and the other sequences in cross-reference for similar sequences and motivation. LINKS Table of n, a(n) for n=1..5. FORMULA A217413(n) = 2^A217414(n) * 11^A217415(n). EXAMPLE A217414(1)=71 and A217415(1)=5, so this sequence's first term is 2^71 * 11^5. It has two each of 0's, 3's, 4's, 6's, 8's and 9's; three each of 1's, 5's and 7's; and five 2's. CROSSREFS Cf.
