 OFFSET 1,3 COMMENTS See explanation of Stolarksy representations in the C. Mongoven link. LINKS C. Mongoven, Description of Stolarsky Representations EXAMPLE The Stolarsky representation of 19 is 11101. In binary this is equal to 29. So a(19) = 29. PROG (PARI) a(n) = {if (n == 1, return (0)); tau = (1 + sqrt(5))/2; mn = 0; while ((m = round(mn*tau)) < n, mn++; ); if (m == n, return (2*a(mn)+1)); mn = 0; while ((m = floor(mn*(1+tau)-tau/2)) < n, mn++; ); if (m == n, return (2*a(mn))); error("neither A nor B !!"); } \\ (cf C.
