Whatever was in there certainly escaped my eyes.

I played two AICs, two X-Wings and an XY-Loop.

couldn't find that short and nice solution. so here is a long one.

after basics and a x-wing on 1's and 6's get you here

Code:
+-------------------+-------------+------------------+
| 25   27(6)  8     | 12  45    3 | 9    247    1(6) |
| 4    237    9     | 8   12    6 | 37   127    5    |
| 125  23     (16)  | 9   45    7 | 346  248    38   |
+-------------------+-------------+------------------+
| 3    9      5     | 7   8     1 | 2    6      4    |
| 7    8      4     | 3   6     2 | 1    5      9    |
| 6    1      2     | 5   9     4 | 8    3      7    |
+-------------------+-------------+------------------+
| 129  24     -1(7) | 6   1237  5 | 347  14789  38   |
| 8    5      16(7) | 4   137   9 | 367  (17)   2    |
| 29   246    3     | 12  27    8 | 5    479    (16) |
+-------------------+-------------+------------------+


(7)r7c3 = (7)r8c3 - (7=1)r8c8 - (1=6)r9c9 - (6)r1c9 = (6)r1c2 - (6=1)r3c3; r7c3 <> 1
-------------------------

Code:
+---------------+------------+----------------+
| 25   267   8  | 12  45   3 | 9     247   16 |
| 4    237   9  | 8   12   6 | 37    127   5  |
| 125  (23)  16 | 9   45   7 | 46-3  248   38 |
+---------------+------------+----------------+
| 3    9     5  | 7   8    1 | 2     6     4  |
| 7    8     4  | 3   6    2 | 1     5     9  |
| 6    1     2  | 5   9    4 | 8     3     7  |
+---------------+------------+----------------+
| 129  (24)  7  | 6   123  5 | (34)  1489  38 |
| 8    5     16 | 4   137  9 | 367   17    2  |
| 29   246   3  | 12  27   8 | 5     479   16 |
+---------------+------------+----------------+


this gives us an xy-wing {2,3,4} which removes 3 from r3c7 (above)
------------------------------

then comes a loop

Code:
+---------------+-------------+-------------------+
| 25   67-2  8  | 12  45    3 | 9     247    16   |
| 4    37-2  9  | 8   12    6 | 37    127    5    |
| 125  (23)  16 | 9   45    7 | 46    248    8(3) |
+---------------+-------------+-------------------+
| 3    9     5  | 7   8     1 | 2     6      4    |
| 7    8     4  | 3   6     2 | 1     5      9    |
| 6    1     2  | 5   9     4 | 8     3      7    |
+---------------+-------------+-------------------+
| 129  (24)  7  | 6   12-3  5 | (34)  189-4  8(3) |
| 8    5     16 | 4   137   9 | 67-3  17     2    |
| 29   46-2  3  | 12  27    8 | 5     479    16   |
+---------------+-------------+-------------------+


(2=4)r7c2 - (4=3)r7c7 - (3)r7c9 = (3)r3c9 - (3=2)r3c2;
r1c2 <> 2
r2c2 <> 2
r9c2 <> 2
r7c5 <> 3
r8c7 <> 3
r7c8 <> 4

----------------------------

leads to this xy-wing - 2,4,9 which removes 4 from r7c7 and r9c2

Code:
+----------------+-----------+---------------+
| 25    67    8  | 12  45  3 | 9    247   16 |
| 4     37    9  | 8   12  6 | 37   12    5  |
| 125   23    16 | 9   45  7 | 46   248   38 |
+----------------+-----------+---------------+
| 3     9     5  | 7   8   1 | 2    6     4  |
| 7     8     4  | 3   6   2 | 1    5     9  |
| 6     1     2  | 5   9   4 | 8    3     7  |
+----------------+-----------+---------------+
| 129   (24)  7  | 6   12  5 | 3-4  89    38 |
| 8     5     16 | 4   3   9 | 67   17    2  |
| (29)  6-4   3  | 12  7   8 | 5    (49)  16 |
+----------------+-----------+---------------+

"Simplest" pattern path I could find was...
Code:
x-wing(1)c49/r19 ; r1c18<>1, r9c158<>1
xy-chain-ish (7=2)r9c5-(2=1)r9c4-(1=2*)r1c4-(2=5)r1c1-(5=4)r1c5-(*24=7)r1c8 ; r9c8<>7
xy-wing(29-4)r9c1,r7c2,r9c18 ; r7c78<>4, r9c2<>4

A 8 cell solution:
Code:
|---------------|-------------|----------------|
| 125  267  8   |(12) 45    3 | 9    1247  (1)6|
| 4    237  9   | 8   12    6 | 37   127    5  |
| 125  236  16  | 9   45    7 | 346  1248   38 |
|---------------|-------------|----------------|
| 3    9    5   | 7   8     1 | 2    6      4  |
| 7    8    4   | 3   6     2 | 1    5      9  |
| 6    1    2   | 5   9     4 | 8    3      7  |
|---------------|-------------|----------------|
| 129 (24)  17  | 6   1237  5 | 347  14789  38 |
| 8    5    167 | 4   137   9 | 367  17     2  |
|(129) 2(4)6 3  |(12) 127   8 | 5  1(4)7-9 (1)6|
|---------------|-------------|----------------|

r1/9c9=1:
r1c9=1 -> r1c4=2 -> r9c4=1
r9c9=1 ->                  =>
r9c1=2/9:
r9c1=2 -> r7c2=4 -> r9c8=4
r9c1=9                     => r9c8<>9
