Most of the terms of this sequence are rather predictable. All the powers of 10 should be in the sequence. Review of the squares of the numbers 1 to 9 suggests that there should be at least a few terms ending in 5 or 6. So it is a pleasant surprise to find 3792 as a term: its square is 14379264. The substring doesn't have to be at the end, as with multiples of 5 or 6, nor at the beginning, as with the powers of 10.
