Ternary Pin Burr by Aleksandr Leontov

I recently received this puzzle that appears to be a complicated Burr but I’m told that there’s a pattern to the solve, we shall see..

Here’s a comical excerpt from Kevin’s blog:

“According to Puzzlewillbeplayed, the N-ary sequence for the Ternary pin burr is 162 moves long which, by the standards of Aleksandr's previous puzzles, really quite short and very pleasant. In just a few minutes I had the sequence worked out and completed with a piece falling onto a cat's head (he barely noticed - another advantage of plastic puzzles):

At this point I had a little blow to the head! It occured to me rather stupidly to try and look inside. This didn't end well as the pieces move against each other very smoothly and easily under gravity alone. I turned it out of the horizontal orientation and peered inside just in time to watch several pieces drop out onto the cat (who began to pay attention). I desperately tried to prevent them from falling out and dislodged several more and it became very unstable and collapsed in a heap on the cat who ran off my lap with rather sharp claws - OUCH (but no Whack!) scattering pieces everywhere.”
