the ultimate square

screenshot of ultimate square in excelMy daughter got a little distracted doing her maths homework this evening, which involved making charts in Excel. She drifted off into the apparently infinitely unfolding edges of the spreadsheet, calling out, “Look mum! I got to 25,000!” and so on as the numbers of the cells grew and grew. Finally, to my surprise, she actually found an edge to Excel’s spreadsheet.

Did you realise that “the ultimate square” of an Excel spreadsheet (as my eleven-year-old has named it) is IV65536?

That’s right. IV is how far across you can get, and 65536 is how far down you can get.

That’s a long way. But it’s not infinite.
