[companion question here]

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

I’ve solved 4 of the 9×9 sub-centers of the dice, and arrived on the step to resolve the 5×5 sub-sub-centers of the remaining two. There is an error within the information guide 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 middle piece of the 5×5 sub-centers. However, the underside left algorithm is inaccurate; it does the identical factor because the aforementioned one. What is the proper algorithm to do right here?
