Nice, Phil, but an all-bivalue DP like this is a BUG-Lite, not a MUG.
M = multi-value, meaning at least one cell in the base pattern must have 3 or more candidates to merit the mean MUG moniker.

Play this puzzle online at the Daily Sudoku site
I'm using Phil's MUG but I call it a potential DP, 39-69-36,r46c357.
2r4c2=8r4c5-(8=5)r5c5-(5=1)r7c5-(1=3459)r4579c4-(49=1)r3c4-(19=2)r3c53=>r4c3<>2
Excuse the notation, I'm not real confident about the 2nd and 3rd terms from the end.

Uses most of Ngisa's cells...
Discontinuous loop (with strong-strong inference) places 2r3c3:
- Code: Select all
(2=9)r3c3 – (9=158)r357c5 – r5c8 = r6c8 – (8=592)r136c3 => -2r2c1,r4c3,r3c6; stte
