Comments

Similar but different sequences are the "Cyclops numbers" A134808 and A032945 and A051022, which are subsequences, except for the 1- and 2-digit terms.

Also, numbers whose decimal representation cannot be split up between any two digits without producing a string with a leading zero (other than "0" itself).

Also, numbers n > 9 such that floor(n/10) is in A011540, i.e., has a digit '0'.
