In the 49x49x49 video, he goes over previous world records of "Highest Order nxnxn Twisty Puzzle", and I thought it was weird he didn't mention the 34x34x34. But in the youtube description, he links to this forum post where he announces it on August 10 (a few weeks before the video, but still well after May 10): https://www.twistypuzzles.com/forum/viewtopic.php?t=39559 There is a comment from the creator of the 34x34x34:
> Ah there's so much I want to say, where to begin? Well, soon after finishing the 34x34, I notified Greg, who immediately notified me about the 49x49. At that point, Preston had already checkered the 49x49, so I did not consider the 34x34 a world record. It seems nobody noticed this, but nowhere in any of my videos did I claim the 34x34 was a world record :lol: But still, everyone just assumed it was :lol:
