Lots of ways to go, like a fat xy chain/turbot fish/x cycle. Or how abt an xyz wing for fun?

Code: Select all: 1 4 678 | 5 68 3 | 9 268 27 | 3 2 678 | 689 1689 169 | 67 5 4 | 68 5 9 | 27 4 27 | 3 68 1 | -------------+-----------------+----------------| 4 7 2 | 936 936 96 | 5 1 8 | 9 6 1 | 28 58 25 | 4 7 3 | 5 8 3 | 47 17 147 | 2 9 6 | -------------+-----------------+----------------| 7 1 5 | 436 2 46 | 8 *36 9 | 268 3 68 | 679 5679 5679 | 1 4 257 | *26 9 4 | 1 3567 8 |-67 *236 257 |

The [6] in [r9c7] can see all the 6's in the wing.

At the end, a BUG+1 or an XY-chain
