Almost Grouped Remote Pair Loop: [(4/7)r5c1 = r7c1 - r7c789 = r8c7 - r46c7 = (4/7)r5c9 - loop *] + (#4)r4c8

(*)
As an AIC: [(4,7)r5c19 = (7,4)r57c1|(4,7)b6p617 - (4)r7c789|(7)r78c7 = (4,7)b9p4123 - (4)r46c7|(7)r7c1 = (7,4)r5c19 - loop]
As a double-digit (Rank 0) fish: (47)C1B69\r57c7

(47)r5c19 == (4)r4c8 - r4c2 = (4,7)r57c1 - (4)r7c1|(7)r7c9 = (47)r5c19 => +47 r5c19; stte

...or using the kraken fish:

(47)C1B69\r57c7 = (4)r4c8 - r4c2 = (4,7)r57c1 - (4)r7c1|(7)r7c9 = (47)r5c19 => -4 r5c4, -7 r4c46; stte

PS. I reopened the related RP-notation discussion here.

PPS. As a side note about the previously discussed fish notation. I think it might be a good idea to use Allan Barker's convention of capitalizing the base sets, as I did above. It makes the fishes stand out more within chains, and it makes it clearer that they're sets instead of cell coordinates. Otherwise, the possibility of confusion is especially prevalent with mutant fishes, like the one above.
