I've worked through Jacob's solution and was successful so it is
certainly easy and useful, especially for beginners. It may even be
useful for handling the corners of the 3-simplex and higher. Do check it
out.

Hi Jacob,

I think you did a good job explaining the method clearly. I have the follow=
ing comments, nothing serious.

(1) You said: "using the following method, you can consistently solve this =
puzzle in 6 moves or less." I don't agree. There are five pieces to be solv=
ed. When the four stickers of a piece are in two 2-swap position, according=
to the paragraph starting with "If only two pieces match..." this piece re=
quires two moves. So the total number of moves is ten, in the worst case. I=
s it right? Since the probability that a certain piece is in such a positio=
n is 1/4, the probability of this worst case is 1/4^5 ~ one thousandth. But=
it will occur.=20

(2) The title of the wiki page is "Simplex 2^4". I like "2 layer simplex" b=
etter, as in the title of this post. "2^4" makes me think of 2x2x2x2 immedi=
ately, so seems to be misleading.

(3) It would be good if you could mention the 3D analog of this puzzle: Pyr=
aminx scrambled by only twisting the trivial tips. People will have an idea=
about what kind of task they are facing.

Thanks for the feedback and I'm glad you understood it well. Actually you w=
ould be right about the two move twists.=C2=A0Before now, I=C2=A0had never =
had more than 2 separate 2 move twists in any solve, and never more than 1 =
if every piece was scrambled, so I assumed that was a pattern like with edg=
es and corners on the Rubik's cube. I actually just had one that needed 8, =
and it was kinda confusing until I went back and noticed that I had 3 separ=
ate 2 twists=C2=A0while every piece was scrambled.=C2=A0The advice about th=
e pyraminx is very smart, but I don't=C2=A0own one. I'll have to make one o=
n UMC and take a screen shot later. For now, I'll go make that quick text=
=C2=A0edit=C2=A0and change the title. (I forgot what I had called it before=
when I made the page, then forgot to change it when I remembered =C2=A0 XD=
)
=C2=A0
