 OFFSET 1,1 COMMENTS Included because A001175 is still a mystery (as are many sequences of the same type). A222414 gives the corresponding values of A001175(a(n)). The maximal value for a prime p > 5 is p-1 if p == 1 or 9 (mod 10) and 2*(p+1) if p == 3 or 7 (mod 10). See Wall's Theorems 6 and 7. These values are given in A253806. - Wolfdieter Lang, Jan 16 2015 Prime(n) is a member if and only if A296240(n) > 1. - Jonathan Sondow, Dec 10 2017 LINKS D. D. Wall, Fibonacci series modulo m, Amer. Math. Monthly, 67 (1960), 525-532. EXAMPLE From Wolfdieter Lang, Jan 16 2015: (Start) a(1) = 29 because A001175(29) = 14 but the maximal value is 29 - 1 = 28. a(2) = 47 because A001175(47) = 32 but the maximal value is 2*(47 + 1) = 96. All other primes p > 5 have A001175(p) = maximal value for p. E.g., p = 11 has A001175(11) = 11-1 = 10 and p = 7 has A001175(7) = 2*(7 + 1) = 16. (End) CROSSREFS Cf.
