Umm, I don't know what EZD algs are, and assuming that this thread was originally asking about SQ-1 to 3x3 algs, I might be able to help.
Sq-1 algs follow the form:
1, 6 / 2, -3 /
Turn the top layer, turn the bottom layer /turn the side/ turn the top layer, turn the bottom layer /turn the side/
In Sq-1, you can turn the top layer less than 90 degrees and still turn the slice. In 3x3, you can't. However, any Sq-1 algs that exclusively have 90 degree turns should be able to be converted into 3x3 algs.
So, double L-perm is the basic CP on Sq-1. You can also do it on 3x3: R2 U' R2 U D R2 D' R2
In Sq-1 notation, it would look something like this: / -3, 0 / 3, 3 / 0, -3 /
I think, anyway. If someone is good at Sq-1 sees something wrong, feel free to provide the correct explanation.
@American-Cuber I hope this answers your question, as I don't know what is actually was in the first place.
