    @elettrona @nationsblind @BPI @mastoblind I know how to do it with the simplest method, layer by layer.I found amazing that this 80's piece of plastic is able to speak to teenagers and kids, like chess.I was able to reduce my young nephew smartphone time with that !I'm curious about your tactile cube.Amongst my cubes, I have an awesome variant called mirror cube, where there are no colour but the layers have different lengths and heights.Same colour translate to same level, you have to go back to a standard Cube shape

    A Friday-afternoon puzzle about #RubiksCube:What's the shortest sequence of moves on the Cube which _non-obviously_ gets you back to where you started?By "non-obviously", I mean that it shouldn't be possible to _prove_ the sequence is a no-op by using only the obvious properties of the quarter-turn moves that they all have order 4, and opposite faces commute.To be group-theoretically formal about it, consider the following infinite group H, which captures those properties of the Cube moves but nothing more subtle:H = ⟨ L,R,F,B,U,D | LR=RL, FB=BF, UD=DU, L⁴=R⁴=U⁴=D⁴=F⁴=B⁴=e ⟩A sequence of moves is _obviously_ the identity if it's the identity even when you do it in H. What's the shortest sequence of moves that is the identity in the true Rubik's Cube group, but _not_ the identity in H?

    I have amended the text of the FEP to clarify a couple of things, but also changed the inheritance logic following this month's WG meeting and subsequent discussion on ActivityPub.space. Instead of recommending that replies inherit context from the object it is in reply to, implementors must find the root node (how, is out of scope; tree traversal or context resolution are two ways that come to mind) and inherit its context. This will simplify context resolution and pave the way for other actions like moving, crossposting, forking, locking, etc. I also added in a blurb about situations in which a context would explicitly not be inherited.
