Almost grouped X-chain (*) in the 4s (rfr1c6)
X-chain [(4)r1c4*=r1c7-r45c7=r45c8-r9c8=r9c56]

4r1c6 - (4=2)r6c6 - (2=84)r2c56 - r2c13 = r3c3 - r3c9 = r8c9 - 4r8c4;
4r3c7 - r3c9 = r8c9 - 4r8c4;

(4=2)r6c6 - (2=48)r2c56 => -4 r1c6,
Then the X chain or the kite on 4s gives the key elimination.
So, combining Cenoman's solution with mine:
4r8c9 = r3c9 - (4=28)r1c27 - 2r1c46 = (24)r26c6 - 4r1c6 = [4r1c4 = r1c7 - r3c9 = r8c9] => -4 r8c4 ; stte

4r1c6 - (4=2)r6c6 - (2=84)r2c56 - r2c13 = r3c3 - r3c9 = 4r8c9
Ouch! Too similar to Cenoman's?
