%N Greatest exponent in prime-power factorization of prime(n) + 1.
%C If a(n)=1 then prime(a(n)) is a term in A049097. - _Zak Seidov_, Jul 20 2016

%e For n=5, the fifth prime is 11, and the prime factorization of 11 + 1 = 12 is 2^2*3. This has exponents 2 and 1, so a(5) is the largest of these exponents, 2. - _Michael B. Porter_, Jul 20 2016
