Line 54: file 8=409359 ============================================================ </pre> (Follow-up on the random placement of the two rooks.)   I re-worked the REXX code and it now has a much more randomness in the (proper) placement of the two rooks. -- [[User:Gerard Schildberger\|Gerard Schildberger]] ([[User talk:Gerard Schildberger\|talk]]) 15:19, 12 May 2014 (UTC) <pre> (1st trial, new code) file 1=269306 =========================================================== file 2=246706 ====================================================== file 3=241984 ===================================================== file 4=240403 ===================================================== file 5=242776 ===================================================== file 6=242128 ===================================================== file 7=245850 ====================================================== file 8=270847 ============================================================ (2nd trial, new code) file 1=269306 =========================================================== file 2=246706 ====================================================== file 3=241984 ===================================================== file 4=240403 ===================================================== file 5=242776 ===================================================== file 6=242128 ===================================================== file 7=245850 ====================================================== file 8=270847 ============================================================ </pre> Many thanks to (user) Steenslag for pointing out the un-randomness of the rook placement in the REXX code.
