A claustrophobic royal knight hunt

Yes, 27 moves are fastest possible way. I made tablebases for this problem. :D It's even better than search tree, because we have only 90 legal positions. Here is one more solution (so we have multiple solutions): 1. Bf1 2. Rg2 3. Kg3 4. Bh2 5. R2g1 6. Bg2 7. Rf1 8. Bg1 9. Rh2 10. Bh1 11. Rg2 12. Kh2 13. Rg3 14. Bg2 15. Kh1 16. Bh2 17. Rg1 18. Bf1 19. R3g2 20. Bg3 21. Kh2 22. Rh1 23. Kg1 24. Rgh2 25. Bg2 26. Kf1 27. Kxe1 The starting position is the only one with 27 moves to make. Interestingly, did the author also made tablebases or smth similar? :)
