Hello SeqFans,
Look at this 9 line-table:
131399 -> 1*31399 = 31399
31399 -> 3*1399 = 4197
4197 -> 4*197 = 788
788 -> 7*88 = 616
616 -> 6*16 = 96
96 -> 9*6 = 54
54 -> 5*4 = 20
20 -> 2*0 = 0
0
Is it possible to find a similar 10-line table where:
a) all lines start with a different digit;
b) the said digit, multiplied by the chain to its right,
gives the integer starting the next line;
c) no integer (except 0) has a leading zero.
Best,
É.
