If you do find other triangle-square numbers, and/or a pattern behind them, do label any spoilers in the comments carefully. • And don't just look them up! • Sorry this is such a quick video. True story: I've been waiting for government paperwork so I can put a different video up, but the wait has gone on too long. This should tide us all over for a bit.
