 So I forgot the tripod again, so you might see the screen go from side to side as I can't keep it still. Anyway, that was 6 minutes under my target time, but I felt so sluggish. Ah, that happened. I just don't know. Perhaps it's because it's a bit cooler. It really is much cooler than yesterday and we're hoping for a bit of rain that still hasn't come. So yesterday I uploaded a video on the product groups. And so today, just to cement that understanding, I thought I'd put up an example and we're just going to look at two permutation groups, really two cyclic groups I should say, and just get the product group of two identical cyclic groups. So give it a watch.
