I was considering Kevink2's number 285714 from BMAD's 50% Increase problem to render 571428 , but hoping for much smaller number . Yet the 6 digits shows up again...."125874...can be shuffled to be 251748" matched with code. What other properties these 6digit combo has? Thanks for convincing solve Pickett..
