单词	TotientValenceFunction
释义	totient valence function Given an integer $n$ , count how many integers $m$ in the set $\\{n+1,n+2,\\ldots n^{2}\\}$ satisfy $\\phi(m)=n$ . This is the totient valence of $n$ , usually labelled $N_{\\phi}(n)$ . (The only two special cases are 2 and 6, for which one has to look a little beyound $n^{2}$ ). Robert Carmichael conjectured that $N_{\\phi}(n)=1$ never. Two sequences in Sloane’s OEIS that list numbers with higher totient valences than preceding numbers are A007374 and A097942.
