Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Numbers n such that if m > n, phi(m) >= phi(n).
%C Conjecture: except for 1,2,3,4, this is the nonzero values of A066362.

%e 10 is in the sequence because phi(10) = 4 and no larger m has phi(m) < 4. phi(12) = 4; it is not smaller.
%Y Cf. A036913, A000010, zeros of A066362.
