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. Other mysterious video along soon!

I'll do a solution video to this one sooner or later.
