 OFFSET 1,1 COMMENTS The 6 members with two digits are also Keith numbers. There are 233 numbers below 10^6 in this sequence. If the number x is rewritten as a U b, the problem is to find a value of y such that x = a*F(y) + b*F(y+1), where F(y) is a Fibonacci number (see file with values of x, a, b, y, for 1 n, ok = 1); if (z == n, return (1)); x = y; y = z; )); } \\ Michel Marcus, Oct 08 2014 CROSSREFS Cf.
