• Numbers using only digits 2 and 3.at n=37A032810
• Replace each 1 in decimal expansion of n with 1 1's, each 2 with 2 2's, etc. (0 vanishes).at n=22A048376
• Numbers n with digits in nondecreasing order such that sum of the reciprocal of digits is an integer.at n=32A091784

• Any digit d in the sequence says: "I am part of an integer in which you'll find d digits d".at n=12A108571
