%N Sum of prime factors (counted with multiplicity) of the period numbers defined by A133900.
%e a(6)=12, since A133900(6)=72=2*2*2*3*3 and 2+2+2+3+3=12.
%e a(12)=19, since A133900(12)=864=2*2*2*2*2*3*3*3 and 2+2+2+2+2+3+3+3=19.
%Y Cf. A000040, A100118, A046363, A133620, A133621, A133623, A133630, A133635.
