%S 5,7,9,11,13,15,16,18,20,21,24,25,26,29,30,32,33,35,37,38,41,41,44,45,

%N Number of partition numbers with n digits.

%C a(n)=A072212(n)-A072212(n-1) for n>=2. - _Emeric Deutsch_, Mar 19 2005

%e a(2)=7 because the number of partitions of 5,6,...,13 are 7,11,15,22,30,42,56, 77,101 and thus exactly 7 partition numbers have 2 digits.

%Y Cf. A000041, A072212.

%K nonn,base

%O 1,1
