I used to be given an 11x11x11 rubik’s dice as a present. It got here with a information ebook that I’ve been following to resolve the dice.

I’ve solved 4 of the 9×9 sub-centers of the dice, and am now on the step to resolve the remaining two. There is an error within the information ebook notation, the place it has duplicate algorithms (circled in crimson) to swap two totally different pairs of items:

The prime proper algorithm is appropriate — it swaps the rightmost heart piece of the 5×5 sub-centers. However, the underside left algorithm is wrong; it does the identical factor because the aforementioned one. What is the right algorithm to do right here?

Similarly, I observed one other pair of duplicate algorithms within the step of fixing the 7×7 sub-centers:

I’ve not examined both of those duplicate algorithms, however I’m guessing that the center-right circled algorithm is appropriate, and want a brand new algorithm for the underside left one within the picture.
