Very cool!

Here's an alternative expression for that UR:

Code: Select all
.-----------------.-----------------.----------------------.
| 8    15     13  | 6    2357  4    |  29     379     17   |
| 2    56     7   | 35   9     18   | (48)+   36      48+1 |
| 4    9      136 | 138  2378  1278 |  2#(8)  367     5    |
:-----------------+-----------------+----------------------:
| 16   146    146 | 89   28    289  |  7      5       3    |
| 9    3      8   | 7    4     5    |  6      1       2    |
| 7    2      5   | 13   36    16   | +9-48   9#(4)  (48)+ |
:-----------------+-----------------+----------------------:
| 3    147    2   | 459  57    79   |  15     8       6    |
| 56   4678   9   | 458  1     678  |  3      2       47   |
| 156  14678  146 | 2    5678  3    |  15     47      9    |
'-----------------'-----------------'----------------------'

UR(48)r26c79 using #externals:

(48)r23c7 == (48)r6c89 => -48 r6c7; stte

Added. Using +internals is just as simple (but I prefer the symmetry of the externals):

(1)r2c9 == (948)r623c7 => -48 r2c9; stte

(9)r6c7 == (148)b3p647 => -48 r6c7; stte

(7=1)r1c9 - 1r2c9 = (16)r26c6 - 6r6c5 = r9c5 - (6=1457)r9c1378 => -7 r13c8 ; stte

Hi Steve! You could (if you wished) replace that with a single node: (687)r9c258

Pretty cool. I like it.

I also considered writing it -6r6c6 = (14567)r9c13678 and letting the reader figure out where the digits had to be. I decided to sacrifice brevity for clarity.
