I submitted the new sequence A112547, in which a(n) counts the k with floor(p(k)/k) = n.
For n = 2, there are 8 primes p(k) with floor(p(k)/k) = 2, namely 2,11,13,17,19,23,29,31. For some inexplicable reason, A072916 does not count 2 among the primes, which would give a(2) = 8 instead of a(2) = 7.
Because of this error, I did not find A072916 when I looked up 3,8,19,41,... Had I found it, I would have extended it rather than creating A112547.
I propose that A072916(2) be changed to 8 and the comments accordingly fixed to include 2 as a prime, which it is.
