Not sure I understand swordfishes, but a <179> ANP in gf

If the Pair <79> in gf is true then e=8, d=6, c=4, b=1
If the Pair <79> in gf is false then g=1
either way a is not <1> to solve

Code:

+------------+----------------+-----------+
| 8  9   57  |  3    1   57   | 6    2  4 |
| 2  45  457 |  6    789 5789 | 79   3  1 |
| 1  6   3   |  2    4   79   | 79   5  8 |
+------------+----------------+-----------+
| 49 1  d68  | e89   5   2    | 3   c46 7 |
| 49 3   26  | g179 f79  1679 | 124  8  5 |
| 5  7   268 |  4    3   168  | 12   16 9 |
+------------+----------------+-----------+
| 6  2   1   |  78   78  4    | 5    9  3 |

thanks, i was about to comment that a Swordfish is only relevant when 6 (or more) still missing.
here, only 4 1s still missing, so highest fish would be X-wing.
