%N A371030 n written in compositorial base.
%C A371030 Compositorial base is a mixed-radix representation using the composite numbers (A002808) from least to most significant.
%C A371030 Places reading from right have values (1, 4, 24, 192, ...) = compositorial numbers (A036691).
%C A371030 a(n) = concatenation of decimal digits of n in compositorial base. This concatenated representation is unsatisfactory for large n (above 172799), when coefficients of 10 or greater start to appear.
%e A371030 a(35)=123; 35 = 1*24 + 2*4 + 3*1.
