Subject: Re: [MC4D] 2x2x2x2: List of useful algorithms (please add yours)
Date: Tue, 31 Jul 2018 22:25:06 +0100

The list is still very incomplete, only containing cases I found by
generation or by accident. It’s only really useful in LBL/Ortega style
methods, and even then, it can be really hard to recognise cases. However,
you can use RKT style setup moves to transform cases and generate new 1
move longer algs for new cases.

When I next get the chance, I’ll try and sort out some of the algs if
they’re actually broken.
