Mehta

Here are a few example solves to give a sense of how a speed-solve using Mehta would look like. Here is a great ao12 walkthrough by Ethan Davis using CDRLL/JTLE. Many more example solves can be found here (and also here from pages 386 to 400; with the latter pages having more relevant examples). The simulations may take a few seconds to load.

// There seem to be many unoriented corners, so it would likely be a difficult 6CO case to recognise and execute. So we go ahead with DCAL.

// Since we have CP solved, we can go ahead with CDRLL and get a quick case. Also since the DR edge got solved, we could also go for JTLE which would just be a simple OCLL. In this case, both CDRLL and JTLE have the same algorithm, so it doesn't matter much which reasoning was used.
