Happy New Year

I have (almost) always tried to post serious things, so I hereby remark that this is 2*3*5*67 which is the product of 2 by an odd number, and is therefore not the difference of any two whole-number squares. In contrast, last year was 7*7*41 which is 45^2-4^2 as well as being 147^2-140^2 (and one easier pair, left as an exercise for the reader). Next year? Well, there's a whole year to think about it.
