I didn't get the impression that it was symmetrical from the picture, and I was browsing on a phone. I guess it could have been more clearly marked though. Plus, as the other reply noted, the "problem" wouldn't have been a problem if both sides were symmetrical.
- tgb 10y agoI don't think the comment is pointing out the difficulty in telling whether it's meant to be symmetric, it's pointing out that the symmetric case is trivial and so any example should be really different from the symmetric case in order to serve well as an example. It's hard to picture how the climbers might have any difficulty whatsoever when seeing an example that's almost trivial.
