Jump to: navigation, search My art name is Idiomdrottning and I'm also one of the editors at Journal of Games and Puzzle Design.

I want the sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 20, 30, 42, 56, 72, 90, 110... for numbers that are n² or n(n+1) to be in the OEIS. I.e. the sorted, duplicates-deleted union of A002378 and A000290. Don't know how else to phrase this. I was looking for squares and almost squares.
