 A076086 a(1) = 1; a(n) is the smallest multiple of a(n-1) not divisible by 10 which is greater than the digit reversal of a(n-1). In case R(a(n-1)) < a(n-1) then a(n) = 2*a(n-1). 0

 OFFSET 1,2 LINKS Table of n, a(n) for n=1..29. EXAMPLE a(4) = 16 hence a(5) =64 = 4*16 >61. But 64 is > 46 hence a(6) = 2*64 = 128.
