FORMULA
a(n) = A214158(A000045(n)). - Jianing Song, Oct 31 2018
EXAMPLE
a(8) = 362 because 362 is the first number having Fibonacci(8) = 21 as least primitive root.
MATHEMATICA
<< NumberTheory`NumberTheoryFunctions`; a = Table[ Fibonacci[i], {i, 2, 20}]; b = Table[0, {20}]; k = 1; Do[j = FromDigits[ Flatten[ Position[ a, PrimitiveRoot[n]]]]; If[ b[[j]] == 0, b[[j]] = n], {n, 2, 10^6}]; b
