The long way around to get Phil's elimination, using AUR(89)r19c13 with externals 8r1c9 and 9r1c2:
2r3c8 = 2r1c9 – [8r1c9=UR=9r1c2] – (9=42)r56c2 – (2=51)r6c17 – (1=32)r1c7,r3c8 => -2r3c1,r1c9,r9c8; stte

Just an another way to use the externals
8r1c9=9r1c2-(9=425)b4p578-(5=13)r16c7-(3=2)r3c8-(2=8)r1c9=> 8r1c9

Good one, Marty. But what about the AUR internals? 2r1c1 has obvious possibilities, but I couldn't find any chains for 4r1c3.
Any ideas?
