LINKS

Table of n, a(n) for n=0..5.

EXAMPLE

a(0)=6;

a(1)=6 because 6*6 = 36;

a(2)=26 because 36*26 = 936;

a(3)=126 because 936*126 = 117936;

a(4)=62501 because 117936*62501 = 7371117936.

MAPLE

P:=proc(q, h) local a, b, k, n; a:=h; b:=ilog10(a)+1; print(h);

for k from 1 to 10 do for n from 2 to q do

if ((a*n) mod 10^b)=a then print(n); a:=a*n; b:=ilog10(a)+1;

break; fi; od; od; end: P(10^9, 6);
