# How do you mirror algorithms?

If you find a case thats horizontally or vertically mirrored to a case you have an algorithm for, how do you change the algorithm for it to work?

I mean Like for this case:

Can you tell me how to do it myself?

you DON'T need to mirror this one, It's the same case...

Can you link me to a good site for that?

no

This is just a case of general cube understanding.
Don't worry, it comes with time and practice

The case(s) you presented are the same case, just with different colors.
In PBL this is:
U Adjacent swap, D adjecent swap; set up with "two bars in front"

As far as mirroring algs goes: check Chris' pages on Speedcubing.com. There should be a great page on translating algs.

For simple L / R mirrors: just perform your regular alg but with the other hand
I do this with N, J, T, U and A-perms

Edit: as you're quite new to all this I'll play nice and provide the link to Chris' page:

The PBL wiki page is:

I encourage you to work it out pen and paper, it's not that hard.
You can check your solution by either doing it or with: http://www.strangepuzzle.com/mirrors.html
( also the home of JNet cube timer )
